[Direct answer]In the Beijing area, the key factors are three: whether it is during working hours, whether the employee is working at the position assigned by the unit, and whether the unit is aware of and benefits from it. Substituting shifts with the consent of the team leader or supervisor is considered work-related and is usually recognized as a work-related injury; if the substitution of shifts is done without the unit's consent, most courts in practice still tend to recognize it - as long as the employee is actually engaged in the work of the employing unit, the unit benefits from it, and it does not violate prohibitive regulations; the exception is where the employee knowingly substitutes for high-risk positions without qualifications (unlicensed electricians, unlicensed special equipment operators), in which case the risk of recognition significantly increases.

1. Problem background and typical scenarios

A colleague had something urgent and asked you to cover the night shift for him/her. The team leader verbally agreed to it, but when you were operating the machine that night, your finger was crushed—and when you applied for work-related injury compensation, the company backtracked: "You didn't report the shift change, so it's not considered a work-related injury." Covering shifts for others is a frequent source of disputes in work-related injury claims, with employers and employees often having diametrically opposed interpretations of what constitutes a "work-related injury."

II. Key points of contention

First, whether the relief work qualifies as "work-related". Second, the legal effect of shift swapping without the employer's approval. Third, the particularities of relief work performed by unqualified personnel. Fourth, the procedures and evidence requirements for work-related injury recognition.

III. Professional analysis by Henglue Law Firm

The first layer is the legal framework: The core of work-related injury identification is the "three elements" - working hours, workplace, and work-related causes, with the latter serving as the pivot. Article 14 of the Work-Related Injury Insurance Regulations stipulates that "any injury sustained during working hours and at the workplace due to work-related causes" shall be recognized as a work-related injury. In the case of the shift worker, the worker was on duty, in the workplace, and performing the employer's duties at the time of the incident. All formal requirements were met, and the controversy focused on the legitimacy of the "shift work" arrangement. The second layer concerns consensual shift work: A shift supervisor or manager's verbal approval of a shift swap constitutes an internal work arrangement adjustment - the manager's intent represents the employer's position, and the shift work qualifies as "work-related causes," making work-related injury identification generally uncontested. Disputes often arise when the employer later denies knowledge of the arrangement, in which case the shift schedule, WeChat group notifications, and colleague testimonies become key evidence. The third layer involves unapproved private shift swaps: Most judicial opinions hold that unauthorized shift swaps violate attendance regulations but do not preclude work-related injury recognition if the worker actually performs the employer's normal production tasks and the work results belong to the employer, ensuring the causal connection between the injury and work remains intact - disciplinary violations cannot negate work-related injury recognition unless they are unrelated to work (e.g., self-harm during off-duty activities). From another perspective, work-related injury insurance protects occupational risks, not ancillary attendance systems. The fourth layer addresses exceptional circumstances: Injuries involving unqualified special operations positions (e.g., welders performing welding without certifications, forklift operators without licenses) are denied recognition by some courts on grounds of "engaging in activities inconsistent with their qualifications or exceeding work-related causes" or due to the worker's own major faults. However, it should be noted that the employer's fault cannot be shifted to the worker in such cases - the focus of defense lies in "who arranged the shift." The fifth layer concerns procedures and evidence: Apply for work-related injury identification within one year of the accident (employers have 30 days to apply); evidence includes proof of employment relationship, shift and shift swap records (chat logs, schedules, shift handover signatures), injury medical records, and witness statements from colleagues. If the employer denies the employment relationship, arbitration must first confirm it. After recognition, a labor capacity assessment determines disability levels, and compensation is implemented based on the assessment results.

IV. Practical suggestions and legal basis

The first step is to fix the facts of the overtime work: archive the chat records, shift schedules, and handover records as soon as possible. The second step is to apply for work-related injury identification within one year and not wait for the company to "handle it internally". The third step is to first seek arbitration to confirm the disputed labor relations. The fourth step is to file a legal review or administrative lawsuit if the identification is obstructed. The main legal basis: Articles 14, 17, and 19 of the "Regulations on Work-related Injury Insurance", and Article 36 of the "Social Insurance Law of the People's Republic of China"; the specific application shall be subject to the currently effective provisions.

5. Henglue Law Firm's Reminder

Three key points about work-related injuries: 1. Injuries sustained while working are considered work-related. 2. Violating work shift rules does not disqualify a claim for work-related injury. 3. Whether the employer approves or not depends on evidence, not verbal promises. Save shift logs and chat records first. 4. There are exceptions to the rule that unqualified workers cannot work in high-risk positions. The person who assigns the work is responsible for any resulting errors.

VI. Frequently Asked Questions

Q1: Does the company say that if you change shifts without reporting it, it won't be considered a work-related injury under any circumstances?

No. As long as the employee is actually working for the unit and the unit benefits from it, changing shifts due to disciplinary reasons generally does not affect the determination of work-related injuries. Most arguments made by the unit in this regard are not supported by the court.

Q2: Who should bear the liability for compensation if an employee gets injured during overtime work?

After the work-related injury is determined, the work-related injury insurance fund and the employing unit shall pay the benefits in accordance with the law, which has nothing to do with the colleague who took over the shift. The colleague shall not bear the liability for compensation.

Q3: What should I do if I get injured while helping a colleague with work during my shift but haven't signed a contract?

First, confirm the labor relationship: pay slips, work badges, attendance records, and colleague testimonies can all prove the existence of a de facto labor relationship. After confirming this, you can proceed with the work-related injury identification process.

Q4: Can an injury sustained while operating a forklift without a license during a shift be recognized as a work-related injury?

There is a risk of controversy. In some cases, the activities will be considered beyond the scope of work and will not be recognized. However, if the unit arranges the activities despite knowing that the employees do not have the necessary certifications, the likelihood of recognition will increase significantly, and the focus of the debate will shift to the person who arranged the activities.

Q5: What is the application period for work-related injury recognition?

The unit shall apply for compensation within 30 days. If the application is overdue, the employee or his/her close relatives shall apply for compensation within one year from the date of the accident injury. Those who fail to apply within the time limit will lose the right to workers' compensation protection.

The above answer is based on the judicial practice in the Beijing area. The judicial interpretations in other provinces and cities may vary. For specific cases, please refer to the local rules and evidence situations.

If you are facing similar problems, it is recommended that you consult a professional lawyer as soon as possible with the evidence materials, so as to avoid missing the statutory time limit. →Personal injury legal services·Beijing Henglu Law Firm
