[Direct answer]The employee can apply for arbitration if the night shift allowance is part of the salary, stipulated in the company's system, agreed upon in the labor contract, or has been paid regularly for a long time but suddenly stopped. Objectively speaking, there is no unified mandatory amount standard for night shift allowance at the national level, and the standards vary from region to region. In the past, the standard amount implemented in Beijing was not high. Therefore, the prerequisite for claiming compensation are "there is an agreement, a system, or a custom to rely on". At the same time, overtime pay related to night shifts follows a different calculation method and is not in conflict with the allowance. The two should not be confused with each other.

I. Problem Background and Typical Scenarios

Night shift workers in manufacturing, medical care, security, and logistics often work on a two-shift schedule year-round, but there has never been an allowance item on their pay slips. When asked about this by the unit, they reply, "There's no such thing." The controversy over night shift allowances typically revolves around two issues: whether it should exist and whether it's been discontinued. The former depends on legal provisions, while the latter involves breach of contract.

II. Key points of dispute

First, the nature and basis of the night shift allowance. Second, the differences in the chances of success between the two situations of suspending and not paying the allowance. Third, the parallel relationship between night shift overtime pay and the allowance. Fourth, the statute of limitations for claiming and the organization of evidence.

III. Professional analysis by Henglue Law Firm

First, the nature comes first: Night shift allowances are compensatory payments for the physical and mental exhaustion caused by nighttime work, and they form part of the total salary. Once the nature of the allowances is defined, failure to pay them becomes not a "welfare issue" but a "remuneration issue". There are four sources of legal basis: national and local normative documents, clear provisions in labor contracts, rules and regulations formulated and publicly announced in accordance with the law, and long-standing actual practices between the employer and employees (for example, the regular inclusion of night shift allowances in pay slips). Second, two defense and offense scenarios: If the system or contract explicitly stipulates the allowances but the employer fails to pay them, this constitutes withholding wages, and arbitration claims can be directly filed. However, if the allowances have never been paid and there are no regulatory provisions, proving the claim becomes more challenging. In this case, industry norms and local standards can be referenced for application, though the success rate is lower than the former but not impossible. The most favorable scenario is "suddenly stopping payments after years of continuous payment", as historical payment records prove the existence of an agreement, and the suspension of payments constitutes a unilateral reduction of labor compensation. Employees can claim back payments and seek compensation for forced termination based on this. Third, don't overlook overtime pay: If night shift work exceeds legal working hours, overtime pay should be calculated at 1.5-, 2-, or 3-times the statutory rate, which is a separate claim from the allowances. In practice, many employers refuse to pay overtime on the grounds that "it's already included in the night shift allowances", but the allowances are fixed compensation while overtime pay is a statutory obligation. The amounts and legal basis of the two are different, and they cannot be offset against each other - night shift workers must keep separate accounts for these two items. Fourth, statute of limitations and evidence: Wage disputes are not subject to the one-year arbitration statute of limitations during the employment relationship, but claims must be filed within one year after termination. For evidence organization, four key documents are required: shift schedules, attendance records, pay slips, and labor contracts/employee handbooks. Historical payment records are used to prove established practices, and severance settlements are used to confirm the total amount of unpaid wages. Arbitration claims should list the unpaid amounts by year to ensure clarity.

IV. Practical suggestions and legal basis

The first step is to collect the institutional documents and historical pay slips as evidence; the second step is to issue a written notice demanding back pay and keep a record of it; the third step is to separately claim overtime pay and allowances; the fourth step is to file an arbitration request if no agreement is reached, listing the claims by year. The main legal basis includes the relevant provisions of the "Regulations on the Composition of Total Wages", Article 44 of the "Labor Law of the People's Republic of China", Articles 30, 38, and 46 of the "Labor Contract Law of the People's Republic of China", and the relevant regulations on wage payment in Beijing. The specific application shall be subject to the currently effective regulations.

VI. Frequently Asked Questions

Q1: The company said that if there's no night shift allowance system, they won't pay it. Is that legal?

If there are no provisions in the system, the claim will be weaker; but if there are contractual agreements, local regulations, or long-standing issuance practices, the claim for retroactive payment can still be made.

Q2: Is the night shift allowance considered part of the salary?

It does. The night shift allowance is a component of the total salary, and failure to pay it constitutes a labor remuneration dispute, for which arbitration can be applied for.

Q3: Can I still recover the funds that have been suspended for many years?

During the employment period, the right to claim labor compensation is not subject to the one-year statute of limitations; after leaving the job, the claim should be raised within one year and asserted on a yearly basis.

Q4: Can I still claim overtime pay even if I've received the night shift allowance?

Yes. The allowance and overtime pay are calculated separately and in parallel. The unit cannot use the allowance to offset the overtime pay.

Q5: What evidence is the most crucial?

The shift schedule and attendance records verify the fact of night shifts, the pay slips and system documents prove the standard, and the historical issuance records demonstrate the established practice.
