Employment Investigations and Due Diligence in China

What employment investigations involve in China

Employment investigations in China are internal fact-finding exercises into allegations of employee misconduct: fraud, bribery, conflicts of interest, harassment, data leakage, expense abuse or breaches of company rules. They matter because Chinese labour law sets a high bar for dismissal. An employer that wants to terminate summarily under Article 39 of the Labour Contract Law must prove a serious violation of lawfully adopted rules, serious dereliction of duty causing major damage, or another statutory ground, and arbitration commissions scrutinise the evidence closely.

A well-run investigation does several things at once. It establishes facts that can support discipline or dismissal, preserves evidence for possible civil or criminal proceedings, identifies control weaknesses, and supports decisions about whether to report to authorities at home or abroad. A poorly run one can do the opposite: produce unusable evidence, trigger personal information protection breaches, provoke a wrongful dismissal claim, or create problems under China's data and state secrets rules when findings are shared with headquarters.

The legal landscape has tightened in several ways. The Personal Information Protection Law (PIPL) governs collection and use of employee data. The Data Security Law and the PIPL restrict providing data stored in China to foreign judicial or law enforcement authorities without approval. The revised Anti-Unfair Competition Law, effective 15 October 2025, sharpened commercial bribery rules, and Criminal Law Amendment (XII), effective 1 March 2024, extended certain breach-of-duty offences, such as illegally running a competing business and favouring relatives, to managers of private enterprises. These changes create both new tools and new risks for employers.

Employment due diligence is the transactional counterpart. In acquisitions, investments and restructurings, buyers review the target's workforce to identify liabilities, compliance gaps and integration risks. The two disciplines share techniques and a common lesson: in China, employment issues are rarely only employment issues.

Running employment investigations step by step

Most employment investigations follow a similar sequence, although the order and intensity vary with the allegation. Planning before acting is the single most important step.

Suspension during an investigation is common, but should usually be with full pay. Unilateral unpaid suspension, or a demotion imposed before the facts are established, can itself be challenged. A short paid suspension, documented in writing and justified by the need to preserve evidence, is easier to defend.

Interviews need particular care. Employees have no statutory right to bring a lawyer to an internal interview, but they are not obliged to incriminate themselves either, and any suggestion of detention, threats or confiscation of personal property can expose the employer and its investigators to liability. Interviews should be conducted by two people, recorded with consent or minuted accurately, and statements should be reviewed and signed by the interviewee, in Chinese where appropriate.

Evidence, data and cross-border limits

Evidence is where many employment investigations in China succeed or fail. Arbitration commissions accept documentary evidence, emails, chat records, system logs, CCTV footage and witness statements, but they expect authenticity to be shown and the collection to be lawful. Notarisation of key electronic evidence, such as WeChat messages on a company device, is often worthwhile.

The PIPL permits processing of employee personal information where necessary for human resources management under lawfully formulated labour rules, but investigations may also require processing beyond routine HR use, including sensitive personal information such as financial accounts or location data, which requires a specific purpose, strict necessity and, in many cases, separate consent. Employers should rely on clear policies stating that company devices, email and systems may be monitored and accessed, adopted through the democratic procedure and acknowledged by employees. Accessing personal devices or private social media accounts without consent is high risk.

Sharing findings abroad raises further issues. Transfers of personal information to headquarters for investigation purposes may fall within the exemptions in the Provisions on Promoting and Regulating Cross-Border Data Flows of March 2024, for example where necessary for cross-border human resources management, but large or sensitive transfers may need a standard contract, certification or security assessment. Data that is important data or touches state secrets cannot simply be exported. See our cross-border data transfer page.

A separate rule applies when foreign authorities are involved. Under the Data Security Law, the PIPL and the International Criminal Judicial Assistance Law, organisations in China may not provide data, personal information or evidence to foreign judicial or law enforcement authorities without approval from the competent Chinese authorities. This matters when an investigation feeds into a US Department of Justice or SEC inquiry, a UK Serious Fraud Office investigation or similar process. Our cross-border regulatory investigations page explains how groups manage these conflicts.

From findings to discipline and dismissal

Findings only become useful if they can support lawful action. Summary dismissal under Article 39 requires that the conduct falls within a clearly defined category in lawfully adopted rules, or within another statutory ground, and that the evidence proves it. Rules that say "other serious misconduct" without detail, or that were never put through the democratic procedure, give little support.

Before dismissing, the employer must notify the trade union and consider its opinion, under Article 43 of the Labour Contract Law. The dismissal notice should identify the facts and the specific rule breached. The limitation period for labour arbitration is generally one year from when the employee knew or should have known of the infringement, and dismissed employees frequently file claims seeking reinstatement or double severance. See our labour arbitration and litigation page.

Where the misconduct involves bribery, embezzlement or misappropriation, the employer can consider a criminal complaint to the public security authorities. Since Criminal Law Amendment (XII), managers of private enterprises can face criminal liability for some forms of self-dealing that were previously limited to state-owned enterprises. A criminal referral is a significant step that should be coordinated carefully with any civil recovery and with reporting obligations in other jurisdictions. Our internal and government investigations page discusses this further.

A worked example illustrates the sequence. A procurement manager in a Guangdong subsidiary is reported for steering contracts to a supplier owned by a relative. The employer secures email and procurement records under its IT policy, interviews colleagues and the manager, and confirms the undisclosed relationship. Because its code of conduct, adopted through the democratic procedure, classifies undisclosed conflicts as serious misconduct, it notifies the union and dismisses the manager, preserves evidence for a possible criminal complaint and shares a summary with its US parent after confirming that the transfer meets Chinese data rules.

Employment due diligence in transactions

Employment due diligence in China focuses on liabilities that are common, quantifiable and often under-estimated. Typical areas include:

• Social insurance and housing fund. Contributions on a minimum base or through agencies; since September 2025, employee waivers are invalid. See our social insurance, benefits and pensions page.
• Labour contracts. Missing written contracts, which can trigger double wages, and staff entitled to open-ended contracts after two fixed terms.
• Working hours and overtime. Unpaid overtime, unapproved special working hour systems and inaccurate attendance records.
• Labour dispatch and outsourcing. Dispatched workers exceeding 10 per cent of the workforce or filling core roles, and outsourcing that is dispatch in substance.
• Group employment. Staff used by several affiliates; the 2025 SPC Interpretation (II) can make affiliates jointly liable in some circumstances.
• Rules and unions. Handbooks without democratic procedures, union fund arrears and collective contracts.
• Key people. Non-compete and confidentiality coverage, change-of-control terms and equity incentives. See our non-compete obligations page.
• Disputes and investigations. Pending arbitration, collective incidents and open misconduct cases.

Findings should translate into deal protections. Quantifiable exposures can be dealt with through price, specific indemnities or escrow; compliance gaps through pre-closing covenants; and key-person risks through retention arrangements. Warranty and indemnity insurers often exclude known labour issues and certain social insurance liabilities, so buyers should not assume these are covered.

The process itself needs adapting to China. Data rooms are often thin on labour information, so buyers rely on management interviews, payroll and social insurance reconciliations, sample contract reviews and public searches of arbitration and court records. Personal information of target employees should be shared only to the extent necessary, ideally anonymised or aggregated until late in the process, because the PIPL applies to disclosures in transactions and sellers are increasingly cautious. Where the target has several sites, sampling should cover each city, since compliance often differs by location.

Building investigation readiness

The quality of employment investigations depends heavily on preparation done long before any allegation arrives. Employers that have the right rules, policies and processes in place can move quickly and lawfully; those that do not often find that their best evidence is unusable or that a clear case of misconduct cannot support dismissal.

Readiness starts with the employee handbook. Misconduct categories should be specific: undisclosed conflicts of interest, acceptance of gifts above a defined value, falsification of expense claims, unauthorised disclosure of confidential information and refusal to cooperate with an investigation should each be listed and classified by seriousness. Each version should be adopted through the democratic procedure and acknowledged by employees in writing or electronically.

Next come data and monitoring policies. Employees should be told, in a clear notice consistent with the PIPL, that company devices, accounts and systems may be monitored and reviewed for compliance purposes, and how cross-border transfers to group entities will occur. Data retention settings should allow relevant records to be preserved when an investigation starts.

Finally, an investigation protocol should set out who receives reports, how conflicts are managed, when external counsel or forensic providers are engaged, how interviews are conducted, and who approves sharing findings outside China. A short protocol that is followed is better than a long one that is not.

1. Update misconduct categories and adopt them through the democratic procedure.
2. Issue PIPL-compliant monitoring and investigation notices.
3. Confirm data preservation capability for email, chat and device data.
4. Agree escalation routes for allegations involving senior managers or possible crimes.
5. Pre-select forensic, translation and PRC counsel providers.
6. Train local HR and compliance staff on interviews and evidence handling.

Cross-border coordination of employment investigations

Many employment investigations in China are triggered by, or feed into, obligations elsewhere. A US-listed parent may need to assess whether conduct implicates the Foreign Corrupt Practices Act. A UK group must consider the failure to prevent bribery offence and, since 1 September 2025, the failure to prevent fraud offence for large organisations. EU-based groups operate whistleblowing channels under the EU Whistleblowing Directive and national laws. Hong Kong companies may face Independent Commission Against Corruption or Securities and Futures Commission inquiries.

China has no general private-sector whistleblower protection statute equivalent to the EU Directive, although various laws protect informants who report to authorities. Global hotlines that collect reports from Chinese employees must still comply with the PIPL, including transparency and cross-border transfer requirements.

Handling reports well is as important as investigating them. Anonymous reports should be acknowledged where a channel allows it, triaged promptly and investigated proportionately, even when details are thin. Retaliation against a reporter, whether through dismissal, demotion or exclusion, undermines the programme and can support a separate claim. Investigators should also avoid revealing the reporter's identity to the subject, and should record how confidentiality was protected throughout the process. These practices align China operations with the expectations of foreign regulators and auditors reviewing the group's compliance programme.

Legal privilege is a recurring concern. Chinese law does not recognise legal professional privilege in the way common law jurisdictions do, and documents created in China may be obtainable by Chinese authorities. Groups often structure investigations so that offshore counsel direct the work to protect privilege abroad, while recognising that this does not create protection in China. Document creation, report format and distribution lists should be planned with both systems in mind.

How TRW & Co helps with employment investigations

We help multinational and Chinese groups plan and coordinate employment investigations and labour due diligence with China operations. We design investigation plans and protocols, coordinate forensic and data review providers, structure privilege and cross-border data strategies, and prepare findings for boards, auditors and regulators abroad. In transactions, we lead employment diligence workstreams and negotiate the resulting contract protections. As a foreign law firm representative office, we do not issue PRC legal opinions or appear in PRC arbitration, courts or criminal proceedings; where PRC legal advice or representation is needed, we work with licensed PRC law firms and coordinate the overall approach.
