[Direct answer]It cannot be extended at will. The same employer and the same employee can only agree on one probationary period, the duration of which is linked to the term of the labor contract and subject to statutory limits; extending the probationary period after it expires on the grounds of failing the assessment is an illegal second agreement. If the illegal probationary period has already been implemented, the employee may claim compensation based on the standard salary for regular employees and the compensation for the probationary period. If the employer wants to retain the employee for further evaluation, the compliant approach is to strictly evaluate the employee according to the standard for regular employees and handle the matter in accordance with the law, rather than prolonging the probationary period.

I. Problem Background and Typical Scenarios

The three-month probationary period is about to end, and the supervisor said that if the performance doesn't meet expectations, the probationary period will be extended for two more months; or after the probationary period ends, the employee will be transferred to a new position, and the new position will require another probationary period. Workers often don't dare to speak up because they are still in the probationary period, but they don't realize that each "extension" may be an illegal agreement, and the wage gap during the extension period is just wasted money.

II. Key points of contention

First, the one-time principle: the same unit and the same worker can only agree on one probationary period. Whether the transfer of positions or the renewal of the contract exceeds the limit. Second, the time limit: for a contract term of more than three months but less than one year, it shall not exceed one month; for a contract term of more than one year but less than three years, it shall not exceed two months; for a contract term of more than three years or without a fixed term, it shall not exceed six months. Third, the calculation of compensation for illegal agreements: it shall be calculated according to the difference between the regular salary and the probationary salary and the period of performance. Fourth, the conditions for termination during the probationary period: the burden of proof for not meeting the recruitment conditions.

III. Professional analysis by Henglue Lawyers

From the experience of Henglue Lawyers in handling labor dispute cases, the key factors determining the outcome of probationary period disputes lie in three aspects: 1. **Contractual Evidence**: The probationary period must be specified in the written labor contract. Extending the probationary period verbally or signing a separate short-term contract after employment may be deemed illegal. Some employers circumvent regulations by labeling the probationary period as a "training period" or "internship period," but these arrangements are still unprotected under substantive review. 2. **Distinction between extension and second probationary periods**: Extending the probationary period (even if the total duration does not exceed the legal limit) violates the "one-time principle" and is an illegal agreement. Converting to a regular position after the contract expires and re-establishing a probationary period due to a job transfer is also illegal. The probationary period is included in the labor contract term—there is no such thing as an "extracontractual probationary period." 3. **Compensation enforcement**: If an illegal probationary period has already been implemented, the employee can claim compensation based on the regular salary standard and the actual duration of the probationary period. They can also demand the wage difference between the probationary and regular periods. For employers, the correct approach is to clearly state the hiring criteria and obtain signatures during the recruitment process, evaluate performance based on these criteria during the probationary period, and retain assessment records. They should make a decision on retention before the probationary period ends. Employers who repeatedly extend the probationary period as a "risk-free evaluation period" are almost certain to lose in arbitration or litigation.

IV. Practical suggestions and legal basis

The first step is to check the correspondence between the probationary period provisions in the labor contract and the contract term and position, and identify any illegal extensions. The second step is to retain written materials such as the probationary period salary records, evaluation notices, and extension decisions. The third step is to first negotiate with the employer in writing to request correction and compensation for the wage difference. The fourth step is to apply for labor arbitration within one year after leaving the job if the negotiation fails, and claim compensation and wage differences. Main legal basis: Article 19 of the Labor Contract Law of the People's Republic of China (amended on December 28, 2012) regarding the probationary period duration and one-time agreement, Article 20 regarding probationary period wages, and Article 83 regarding compensation for illegal probationary period provisions; the Implementing Regulations of the Labor Contract Law of the People's Republic of China (effective since September 18, 2008) regarding probationary period calculation; specific application shall be subject to the currently effective provisions.

5. Henglue Law Firm's Reminder

There are three key points to protect your rights during the probationary period: there is only one probationary period in the same company, and any extension of the probationary period is illegal; if the probationary period has been extended illegally, the employee can claim compensation, and the compensation amount shall be calculated based on the regular salary; written materials determine the outcome of the dispute, and the extension notice is the key evidence.

VI. Frequently Asked Questions

Q1: If I am asked to extend my probation period by two months before it ends, can I refuse?

Yes. Extending the probationary period violates the rule that the same employer can only agree on it once with the same employee, and the employee has the right to refuse it. If the probationary period has actually been extended, the employee can claim compensation and the difference in wages according to the standard for regular employees.

Q2: What is the maximum length of the probationary period for a three-year contract?

The probationary period for labor contracts with a term of more than three months but less than one year shall not exceed one month; for those with a term of more than one year but less than three years, it shall not exceed two months; and for fixed-term and open-ended contracts with a term of more than three years, it shall not exceed six months, and it shall be included in the contract term.

Q3: If I am transferred to a new position after passing the probation period, do I need to go through the probation process again?

No. The probation period once agreed upon cannot be reset due to a job transfer. It is an illegal agreement to re-agree on a probation period after a job transfer. The employer may evaluate the performance of the new position within the job description and assessment system, but cannot set another probation period.

Q4: How to compensate for violating the probation period agreement?

For those who have already fulfilled their obligations, the employer shall pay the worker compensation according to the worker's regular wage standard for the period exceeding the statutory probationary period; the wage difference and compensation may be claimed together.

Q5: What should I do if I'm dismissed during the probationary period on the grounds of being unqualified?

The unit needs to provide evidence that the employment conditions have been clearly informed to the employee, that there is a basis for the assessment, and that the employee indeed does not meet the requirements. If the unit fails to provide such evidence, the dismissal will be deemed illegal, and the employee may demand continued performance of the contract or claim compensation at twice the standard of economic compensation.
