Suspected fake sick leave in China is one of the most difficult HR issues for employers. On one hand, employees have legal protections when they are genuinely ill or injured and need medical treatment. On the other hand, employers are not required to tolerate forged documents, dishonest absence, repeated non-compliance with leave procedures, or misuse of sick leave for unrelated personal activities.
The risk is that employers often move too quickly. A manager may see an employee posting travel photos, working for another company, or submitting a questionable medical certificate and immediately want to treat the absence as misconduct. In China, that can be dangerous. A medical certificate may carry evidentiary value, medical treatment period rules may restrict termination, and medical information is sensitive personal information.
The safest approach is not to “prove the employee is lying” based on suspicion. Employers should build a lawful process: define sick leave rules in the employee handbook, verify documents through appropriate channels, protect medical privacy, collect evidence carefully, communicate with the employee, and only consider discipline or termination when the facts, policy basis, and procedure can withstand labor arbitration review.
Quick answer: what should employers do when they suspect fake sick leave?
When employers suspect fake sick leave in China, the first step is to separate suspicion from evidence. The company should not immediately reject the leave, stop pay, label the employee absent without leave, or terminate employment unless it has a clear legal and policy basis.
| Employer concern | Safer first response | Risk if handled badly |
|---|---|---|
| The sick leave certificate looks unusual. | Check whether the certificate is complete, properly sealed, and consistent with hospital format and leave dates. | Rejecting a valid certificate too quickly may create wage and attendance disputes. |
| The employee refuses to provide medical documents. | Ask for missing documents in writing, cite the company policy, and give a reasonable deadline. | Immediate punishment without notice may look procedurally unfair. |
| The employee is seen traveling or working elsewhere. | Collect lawful evidence and ask the employee to explain before deciding whether the conduct conflicts with the sick leave basis. | Unlawful surveillance or privacy violations may weaken the employer’s case. |
| The employee takes repeated sick leave around holidays or deadlines. | Review leave history, document patterns, and apply a consistent verification process. | Pattern alone usually does not prove fake sick leave. |
| The company wants to terminate. | Check Article 39 misconduct basis, handbook validity, evidence quality, medical treatment period status, and internal approval. | Weak evidence may lead to wrongful termination compensation or reinstatement risk. |
Why fake sick leave is hard to regulate in China
Fake sick leave is hard to manage because several legal issues overlap. A sick leave case may involve attendance, payroll, medical certificates, employee privacy, medical treatment period protection, and termination procedure at the same time.
For ordinary sick leave and medical treatment period rules, employers should first understand the broader framework in this China sick leave and medical treatment period guide. That framework matters because not every suspicious case is misconduct. Some employees may have genuine illness but poor documentation. Others may have valid medical documents but fail to follow the employer’s internal procedure. A smaller group may use forged documents or dishonest behavior to obtain leave.
These scenarios should not be treated the same way. The employer’s response should depend on what is actually proven.
| Scenario | What it may indicate | Recommended employer approach |
|---|---|---|
| Late certificate submission | Administrative non-compliance, not necessarily fraud. | Request supplement, issue reminder or warning if policy allows, and keep payroll/attendance records. |
| Certificate dates do not cover the full absence | Part of the absence may be unsupported. | Ask for clarification and additional documents before treating uncovered days as unauthorized absence. |
| Hospital cannot verify the document | Possible forged or altered certificate. | Keep written verification records, ask the employee to explain, and escalate internally. |
| Employee works for another employer during sick leave | Possible misconduct, especially if it affects the original employer or conflicts with illness claims. | Collect evidence, check handbook rules, and review Article 39 grounds before discipline. |
| Repeated long-term sick leave | May be genuine illness, medical treatment period issue, or abuse. | Track medical treatment period, request updated documents, and avoid termination without legal review. |
Start with a valid sick leave policy and employee handbook
Employers have much stronger control over suspected sick leave abuse if the sick leave procedure is written clearly before the dispute happens. A vague policy such as “employees must provide medical proof” is usually not enough.
Under Article 4 of the Labor Contract Law, employers should establish and improve labor rules and regulations, and rules directly affecting employee interests should be handled through the required consultation and communication process. For sick leave disputes, this means the handbook should not only contain rules, but the employer should also keep evidence that employees received, understood, or acknowledged them.
A strong sick leave policy should define:
- how employees must notify the company when they are sick;
- who receives the sick leave application;
- what medical certificate or sick leave note must be provided;
- whether the document must be from a qualified hospital or medical institution;
- whether the document must include the employee name, diagnosis or medical reason where legally appropriate, recommended rest period, doctor information, issue date, and hospital seal;
- when original documents, scans, or system uploads are acceptable;
- how extensions of sick leave must be requested;
- what happens if documents are incomplete, late, altered, or inconsistent;
- when the company may request supplementary medical records or reasonable re-examination;
- how the company handles suspected forged documents or dishonest absence;
- what level of misconduct may justify warning, unpaid absence treatment, or termination;
- how employee medical information will be protected.
For employers building an evidence-based HR system, the broader HR documentation requirements in China are also important. Sick leave cases often turn on whether the employer can produce the handbook, policy acknowledgment, leave applications, medical documents, attendance records, payroll records, warning letters, investigation notes, and employee explanations.
How to verify a suspicious sick leave certificate
If the employer has reasonable doubts about a sick leave certificate, it may take proportionate steps to verify the document. The goal should be to verify authenticity, not to collect unnecessary details about the employee’s private medical condition.
Practical verification may include checking whether:
- the hospital or clinic exists and is qualified;
- the certificate format matches the institution’s usual format;
- the document contains the required seal or stamp;
- the doctor works at the relevant medical institution;
- the date, certificate number, or registration information is consistent;
- the leave period matches the stated medical advice;
- there are obvious alterations, inconsistent fonts, missing seals, or suspicious signatures.
If the employer contacts the hospital, the request should be limited and formal. The employer can ask whether the certificate was issued by that institution or whether the document details match hospital records. The employer should avoid demanding unnecessary diagnosis details or pressuring medical staff to disclose information beyond what is needed to verify authenticity.
The verification attempt itself should be documented. HR should record the date, contact channel, person contacted, information requested, response received, and any refusal by the hospital to verify. If the hospital refuses to disclose information because of privacy or internal rules, that refusal does not automatically prove the certificate is fake.
Protect employee medical privacy during the investigation
Medical information should be handled carefully. China’s Personal Information Protection Law treats medical and health information as sensitive personal information and requires specific purpose, necessity, and strict protection measures when processing sensitive personal information.
For employers, this means the company should not collect every medical record simply because it is curious or suspicious. HR should limit collection to what is necessary for leave approval, payroll treatment, statutory benefit administration, return-to-work review, or investigation of suspected misconduct.
Good privacy practice includes:
- limiting access to HR, payroll, legal, or management personnel who genuinely need the information;
- avoiding disclosure of the employee’s condition to unrelated managers or coworkers;
- storing medical certificates separately from general personnel files where practical;
- using secure transfer channels for medical documents;
- documenting why the information is collected and how long it will be retained;
- avoiding unnecessary sharing with overseas headquarters unless cross-border transfer requirements are reviewed.
Privacy control is not only a data-compliance issue. It also affects the employment dispute. An employer that investigates fake sick leave aggressively but mishandles medical information may weaken its own position.
Can an employer request a re-examination?
A re-examination can be useful where there are reasonable doubts about the employee’s condition, repeated long-term sick leave, or documents that do not clearly support the requested absence. However, the employer should not treat re-examination as an unlimited right.
The request is stronger if the company’s handbook or employment policy clearly states when a re-examination may be requested and how it will be arranged. The request should also be reasonable in practice.
Employers should consider:
- whether there is a concrete reason for doubt;
- whether the selected hospital is qualified and reputable;
- whether the company will pay the re-examination cost;
- whether the employee is medically able to attend;
- whether the employee receives reasonable notice;
- whether the process protects medical privacy;
- whether the same rule has been applied consistently to similar cases.
If the employee refuses a reasonable re-examination without a valid reason, the refusal may become relevant evidence. But the refusal should not be treated as automatic proof of fraud unless the policy, facts, and procedure support that conclusion.
Can employers conduct home visits or workplace checks?
Home visits may be appropriate in some long-term sick leave cases, but they should be handled with care. A home visit should not become harassment, intimidation, or private surveillance.
A reasonable home visit may be used to show concern, understand whether the employee needs support, confirm whether documents need updating, or discuss return-to-work arrangements. HR should normally arrange it in advance or handle it in a respectful, proportionate way.
Employers should avoid:
- secret filming inside private spaces;
- pressuring neighbors, family members, or unrelated people;
- disclosing the employee’s medical condition to others;
- repeated visits that could be seen as harassment;
- threatening the employee before the facts are clear;
- using invasive tracking methods without legal review.
If the employer discovers facts that clearly conflict with the sick leave basis, such as the employee working elsewhere, traveling in a way inconsistent with the medical certificate, or refusing to provide updated documents, HR should record the evidence lawfully and ask the employee for an explanation before deciding on discipline.
What evidence should employers collect?
In a China labor dispute, suspicion is not enough. The employer needs a complete evidence chain showing the policy basis, the facts, the investigation process, the employee’s opportunity to respond, and the proportionality of the employer’s action.
| Evidence type | What to keep | Why it matters |
|---|---|---|
| Policy basis | Employee handbook, sick leave policy, disciplinary rules, employee acknowledgment, policy training records. | Shows the employee knew the procedure and consequences. |
| Leave records | Sick leave applications, approval records, absence dates, extension requests, return-to-work communication. | Shows whether the employee followed the required process. |
| Medical documents | Certificates, hospital notes, supplementary records, re-examination records where applicable. | Shows what medical basis was provided and whether it covered the absence. |
| Verification records | Hospital verification attempts, written responses, call logs, emails, document-format checks. | Shows that the company investigated before deciding. |
| Employee explanation | Written requests for clarification, employee response, meeting notes, refusal records. | Shows procedural fairness and avoids one-sided conclusions. |
| Payroll and attendance records | Sick pay calculation, unauthorized absence treatment, deductions, payslips, attendance reports. | Connects HR decisions to payroll treatment and reduces wage disputes. |
| Internal approval | HR/legal review, manager approval, trade union notification where applicable, final decision memo. | Shows the company considered legal risk before discipline or termination. |
When can suspected fake sick leave become misconduct?
Suspected fake sick leave may become misconduct when the employer can prove dishonest conduct or serious violation of valid company rules. This may include forged medical certificates, altered documents, false statements, refusal to provide required documents after repeated notices, working for another employer during sick leave in a way that seriously affects the original employment, or other conduct clearly defined as serious misconduct in the handbook.
Article 39 of the Labor Contract Law allows termination in certain employee-fault situations, including serious violation of employer rules and other specified grounds. But this does not mean every suspicious sick leave case justifies immediate termination. The employer still needs a valid rule, employee awareness, reliable evidence, proportionality, and proper procedure.
Employers should ask four questions before treating fake sick leave as serious misconduct:
- Does the company handbook clearly define the conduct as a serious violation?
- Was the handbook lawfully adopted, published, or acknowledged by the employee?
- Is the evidence strong enough to prove the employee’s dishonest conduct?
- Was the disciplinary decision proportionate and consistent with previous cases?
If the answer to any of these questions is weak, the company should consider a lower-risk response, such as a written warning, requiring supplementary documents, treating only uncovered days as unauthorized absence, or negotiating a mutual resolution where appropriate.
How medical treatment period protection affects fake sick leave cases
Medical treatment period protection does not give employees permission to forge documents or abuse leave. However, it does restrict employer action where the employee is genuinely ill or injured and is within the statutory protected period.
The official sick leave and medical treatment period rules explain that employees who need treatment for illness or non-work-related injury may be entitled to a medical treatment period, with national rules providing a framework from 3 to 24 months depending on service history. Shanghai applies its own local medical-treatment-period method, while sick leave pay should be assessed under the current wage-payment rules, employment terms, valid company policies and applicable statutory minimum protection.
Shanghai employers should also note that two long-standing local sick leave pay notices expired on August 15, 2026. See our guide to the Shanghai sick leave pay changes in 2026 for the current position.
Under Articles 42 and 45 of the Labor Contract Law, employees within the prescribed medical treatment period receive protection from certain termination grounds, and fixed-term contracts may need to be extended until the relevant protected circumstance ends.
The key distinction is this: medical treatment period protection restricts no-fault termination and contract expiry treatment, but it does not automatically block all misconduct discipline. If the employer is relying on misconduct, the case should be built as a proven disciplinary case, not as a disguised attempt to terminate an employee because of illness.
What employers should not do
Many fake sick leave disputes are lost because the employer overreacts. Even when the employee’s conduct is suspicious, the company should avoid actions that create a separate legal problem.
| Do not | Why it is risky | Safer alternative |
|---|---|---|
| Declare the sick leave fake based only on suspicion. | Suspicion is not evidence, especially when a medical certificate exists. | Verify the document, request explanation, and collect evidence. |
| Immediately stop salary or benefits. | Incorrect payroll treatment can create wage arrears and benefit disputes. | Review whether the leave is approved, unsupported, or unauthorized before payroll action. |
| Force the hospital to disclose diagnosis details. | Medical information is sensitive and disclosure may be restricted. | Ask only whether the certificate is authentic and properly issued. |
| Use intrusive surveillance. | Privacy violations may undermine the employer’s case. | Collect lawful, proportionate, and relevant evidence. |
| Terminate before giving the employee a chance to explain. | Procedural unfairness can create wrongful termination risk. | Send a written notice, request clarification, and hold a documented meeting. |
| Apply rules that were never communicated. | Uncommunicated policies may be weak in arbitration. | Use properly issued handbook rules and employee acknowledgments. |
How should payroll handle suspicious sick leave?
Payroll should not make independent disciplinary decisions. HR should first determine whether the absence is approved sick leave, unsupported sick leave, unauthorized absence, or confirmed misconduct. Payroll treatment should follow that determination and be documented clearly.
For example, if the employee provides a valid sick leave certificate, sick leave pay may apply according to local rules, employment contract terms, and company policy. If part of the absence is not covered by medical documentation after reasonable requests, the uncovered days may require separate handling under the company’s attendance policy. If fraud is proven, the company may consider disciplinary action and payroll adjustment based on the facts and applicable rules.
For companies with complex leave records, multiple China cities, or limited local HR capacity, China payroll outsourcing can help align sick leave records, sick pay, IIT, social insurance, housing fund, payslips, and payroll reports with documented HR decisions.
Practical workflow for employers
Employers should build a repeatable workflow rather than improvising each time a manager suspects fake sick leave.
| Step | Employer action | Key record to keep |
|---|---|---|
| 1. Identify the concern | Record what triggered the suspicion: document issue, absence pattern, inconsistent activity, or refusal to cooperate. | Initial incident note. |
| 2. Check policy basis | Review the employee handbook, sick leave policy, and disciplinary rules. | Relevant handbook clauses and acknowledgment proof. |
| 3. Request clarification | Ask the employee to provide missing documents or explain inconsistencies. | Written request and employee response. |
| 4. Verify documents | Check certificate authenticity through lawful and proportionate channels. | Verification log and hospital response if any. |
| 5. Review privacy | Limit access to medical information and avoid excessive collection. | Internal access and storage record. |
| 6. Assess employment status | Check medical treatment period, contract status, protected status, and payroll implications. | HR legal review memo. |
| 7. Decide response | Choose warning, request for supplement, unauthorized absence treatment, mutual discussion, or disciplinary action depending on evidence. | Decision memo and approval record. |
| 8. Communicate outcome | Notify the employee clearly and respectfully. | Written notice and delivery proof. |
How HROne supports employers managing sick leave risk
Foreign companies often struggle with fake sick leave cases because the decision is split across offshore HR, local managers, payroll vendors, and legal advisers. This makes evidence inconsistent and increases the risk of overreaction.
For companies with a China entity, China PEO services can support day-to-day HR administration, employee records, payroll coordination, compliance inquiries, and escalation of sensitive HR matters while the client remains the legal employer.
For companies without a local China entity, China EOR services can provide a local employment framework covering compliant employment contracts, payroll processing, statutory filings, HR administration, and ongoing compliance management.
In either model, the goal is not to “catch” employees. The goal is to manage sick leave fairly, protect genuine medical rights, reduce abuse, and ensure that any employer action is supported by policy, evidence, payroll records, and lawful procedure.
Conclusion
Fake sick leave in China should be managed through evidence, not instinct. Employers can regulate suspected abuse, but they must do so through clear handbook rules, lawful document verification, privacy protection, consistent communication, payroll accuracy, and careful termination review.
The strongest employer position is built before the dispute begins. A clear sick leave policy, properly issued employee handbook, complete attendance records, controlled medical data processing, and coordinated HR-payroll workflow make it much easier to handle suspicious cases without violating employee rights.
When the facts support misconduct, employers may have legal options. When the facts are unclear, a cautious, documented, and proportionate approach is usually safer than immediate termination.
FAQ
Can an employer reject sick leave in China if the certificate looks suspicious?
An employer should not reject sick leave based only on suspicion. If the certificate looks suspicious, the employer can request clarification, ask for supplementary documents, verify authenticity through appropriate channels, and document the process before deciding whether the absence is approved, unsupported, or unauthorized.
Can an employer verify a sick leave certificate with a hospital in China?
An employer may attempt to verify whether the certificate was issued by the hospital and whether basic document details are authentic. However, hospitals may refuse to disclose medical information due to privacy and internal rules. Employers should focus on authenticity verification rather than requesting unnecessary diagnosis details.
Can fake sick leave justify termination in China?
Fake sick leave may justify disciplinary action or termination if the employer can prove serious misconduct, such as forged documents or serious violation of valid company rules. The employer needs a clear handbook rule, employee acknowledgment, reliable evidence, proportionality, and proper procedure.
Can employees be terminated during the medical treatment period for fake sick leave?
Medical treatment period protection restricts certain no-fault termination grounds, but it does not automatically protect proven misconduct. If the employer relies on misconduct, the case should be based on strong evidence and valid disciplinary rules, not simply on the fact that the employee is taking sick leave.
Can an employer request a re-examination?
An employer may request a reasonable re-examination if the company policy allows it and there are concrete doubts about the sick leave. The request should be proportionate, based on a qualified medical institution, respectful of privacy, and ideally paid for by the employer.
What should a sick leave policy in China include?
A China sick leave policy should define notification procedures, required medical certificates, submission deadlines, extension rules, re-examination conditions, verification rights, privacy protection, payroll treatment, unauthorized absence rules, and disciplinary consequences for false documents or dishonest conduct.
