In the past, when many factories and units were reformed, many workers and friends had experienced the matter of "buying out their seniority." To put it simply, the employer gives a sum of money to terminate the labor relationship with the employees. Many people thought at the time that once the money was taken and signed, the matter was completely over and they would have nothing to do with the employer in the future.
But after ten or twenty years, when I was about to retire and went through the retirement procedures, I realized something was wrong: the compensation I received seemed to be a lot less; the social security I paid during the years I worked was not enough, and was even interrupted for many years; I had obviously worked for more than ten years, but my seniority was underestimated by several years, which directly resulted in a pension loss of several hundred dollars a month.
At this time, many people will feel that it has been so long, the words have been signed, and the money has been taken, they will definitely not come back, and they will only suffer a loss. But I tell you today in the most practical and down-to-earth terms: Buying out the length of service is really not a one-time transaction. Most of the undercalculated money, missed social security payments, and miscalculated length of service can be recovered as long as you follow the rules.
This article does not use difficult official language or professional provisions. It uses words that ordinary people can understand. It explains completely and clearly how to check, how to calculate, who to ask for, and what to prepare, so that everyone can have peace of mind, know that their rights and interests have not been lost, and know how to get them back step by step.
1. Let’s explain the truth first: just because you sign, it doesn’t mean that all your rights are gone.
The most troubling point for many people is: I signed the agreement myself and received the money, can I still find another employer now? Doesn't it count?
Let me explain the most important truth first:
Buying out the length of service essentially means that the company and the employee have agreed to quit and separate. The compensation that the company should pay, the social security that should be paid, and the number of years of service that should be calculated are all required by the state. It cannot be just what the company says, nor can it be deducted casually after signing.
The state has long stipulated that units are not allowed to withhold social security payments from employees, undercount seniority, or withhold compensation in the name of "buying off their seniority." Even if the agreement back then said "I will no longer contact the employer" and "I am responsible for social security", as long as the employer fails to comply with national regulations, these words will not count legally.
For example, if your employer deliberately reduces your length of service, only compensates you based on basic salary, and does not pay you any social security for so many years of work, even if you sign it, the agreement is untenable and you can still ask your employer to get back what belongs to you.
Some people are also worried that it has been more than ten or twenty years, can they still want it?
Don't worry, everyone, there is no saying that social security and length of service cannot be applied for after a certain number of years. As long as you can prove that you worked in this unit that year, you can verify, re-apply and re-pay at any time when you discover it.
To sum it up in one sentence: you can sign it, but the treatment prescribed by the state cannot be less, and it has not affected your rights protection even after so long.
2. The three things that everyone is most likely to suffer from: money, social security, and length of service
Over the years, friends who have bought out their seniority have suffered the most from three things: less compensation, insufficient social security payments, and missed calculations of seniority. I will break it down one by one and explain it in plain English so that everyone can compare and understand it by themselves.
1. Underpayment of compensation: This is the most common and easiest thing to get back
During the buyout that year, the compensation amount given by the employer had a fixed algorithm and was not just a random number given by the employer. Many units take advantage of people's lack of understanding of policies and deliberately give less.
The correct algorithm is very simple:
If you work in the company for one year, you will be given one month’s salary;
If you have worked for more than half a year but less than one year, it will be counted as one year; if you have worked for less than half a year, you will be given half a month’s salary;
The salary here is not the basic salary, but the average of all the money you get throughout the year, including basic salary, bonuses, overtime pay, year-end bonuses, and various subsidies, all calculated together.
But how do many units deceive people?
Obviously you have worked for 15 years, but I only count it as 10 years;
Obviously your monthly income adds up to 5,000 yuan, but the basic salary is only 2,000 yuan.
The probation period, time on waiting list, and time on leave without pay are not directly counted as seniority;
The compensation money is mixed with the resettlement fee and living expenses, and everyone is fooled into saying that this is all.
To give the most practical example:
You have worked for the company for 20 years, and the total income in the year before you resigned averaged 6,000 yuan per month. Then the compensation you deserve is 20 × 6,000 = 120,000 yuan.
But the employer only gives you 3,000 yuan per month, and only gives you 60,000 yuan. The 60,000 yuan less is the money you can legally get back now.
As long as you can show your salary slips, bank statements, and proof of seniority for that year, your employer must make up the difference.
2. Failure to pay social security or breaking off social security: directly affects how much money you will receive when you are old.
Social security, for us people, means pension money and medical money, which are more important than one-time compensation.
Many people didn't pay attention at all when they bought out. The employer just gave them a sum of money, and they didn't pay social security at all during the years they worked, or they stopped paying it for many years. When they were about to retire, they found out after a check that the payment period was not enough, the pension was very small, and the medical insurance did not meet the standard of free life-long insurance.
Here are the two most practical points for you:
First, as long as you work at the company, the company must pay you social security. The buyout agreement cannot exempt you from this responsibility. Regardless of whether it is written in the agreement or not, if the unit fails to pay, it is a violation and it must be repaid.
Second, there is no time limit for social security repayment. It does not mean that repayment cannot be done after 5 or 10 years. As long as the labor relationship can be proved, it can be done now.
Some people may ask: What should I do if my company has already gone bankrupt, closed down, or been cancelled? Don’t be afraid. If this happens, the state has regulations:
If the company goes bankrupt, social security and compensation money will be paid first, before other arrears;
If the unit is canceled before liquidation, the original boss and shareholders will be held responsible;
In fact, if no one is responsible, the social security fund can also help cover the co-ordination part first, so that employees will not suffer losses in vain.
The consequences of not paying enough social security are very real:
If you pay less for pension insurance for a few years, your monthly pension will be several hundred dollars less after retirement, and you will receive it for a lifetime;
If you don’t pay for medical insurance for enough years (20 years for women and 25 years for men in most places), you have to pay for medical treatment after retirement and cannot enjoy lifelong medical insurance;
Unemployment and work-related injuries have not been paid, and all the subsidies that should have been enjoyed that year are not available.
Therefore, if you fail to pay social security or break off social security, you must make up for it. This is a major event related to the rest of your life.
3. Length of service is undercalculated and service breaks: less pension is received because of seniority.
When everyone is planning to retire, they will find that the level of pension depends entirely on the length of service (years of payment). The longer the service period, the higher the pension.
The problem that many people encounter is that they have worked in the company for more than ten years and then pay social security after buying out. The previous years of service have not been taken up and are directly cleared. When retirement is calculated, the pension is much less than others.
Let me explain it clearly to you:
The buyout only terminates the working relationship, and the length of service will not be cleared. The previous length of service and the subsequent years of social security payment must be added together.
For state-owned enterprises and old units, the length of service before establishing a personal social security account with the state can be counted as "deemed payment years", which is equivalent to having already paid social security;
Military service, time spent in the countryside, normal transfers, and time on duty can all be counted as seniority.
The most troublesome situation is: the files are lost, the file materials are incomplete, and the length of service cannot be determined. Don’t panic if this happens, there’s nothing you can do to fix it. As long as you can come up with these things, you can still re-certify your seniority:
Recruitment form and employment registration form for the current year;
Salary slips, bank salary statements;
Work certificate, employment certificate, trade union certificate, attendance sheet;
Certificates from old colleagues in the unit and employment records of the unit kept in the archives;
Relevant documents for unit reform and restructuring.
Nowadays, human resources and social security departments in various places have special channels. As long as the materials can prove that you have worked, you can make up for the missed years of service, and your pension will be recalculated and repaid.
Three or four-step process: no money, less legwork, it can be done step by step
After talking about what you can get back, let’s talk about the most practical steps. There is no charge for the whole process, and there is no need to find connections. Just follow these four steps and ordinary people can do it by themselves.
The first step: do the math yourself and get all the materials.
Before doing things, you should know what you are doing first, and don’t go looking for someone in a haphazard manner.
1. Calculate the compensation difference: Calculate the amount of money you deserve based on "service length
2. Check social security: Use your mobile phone to log in to the national social security service platform and local social security APP, you can check how many years you have paid and which month you have not paid, and print it out;
3. Check the length of service: Check how many years you have worked from joining the company to the time of buyout, and whether there are any gaps in the file.
Materials that must be found (don’t throw away old things at home):
Employment, recruitment, labor contract and other things proving that you work here;
Salary slips, bank statements, and bonus records;
The buyout agreement signed that year and the proof of receiving the money;
Social security payment records and relevant materials in files.
You can find the original materials if you can't find them. If you can't find them, you can go to your unit, archives, or human resources and social security bureau to have them copied and stamped, and they will still work.
Step 2: Discuss with the original unit first. It is easiest to resolve the matter privately.
If the original unit is still there, or it has been changed to another company, and there is a superior supervisory unit, go to them first to communicate.
No need to argue, just say it honestly:
How much was the undercompensation that year?
How many years have you not paid social security?
Which period of service is omitted?
Briefly explain the policy and show them the materials. It's best if we can discuss it well. Be sure to write the agreement in writing, sign it and seal it. Don't rely on verbal promises.
If the unit ignores you and pushes back or blocks you, just take the next step.
Step Three: Complain for free! Ask the Labor Inspection Brigade for help
This step is completely free and is a channel specifically used by the state to help ordinary people get their labor benefits back. You just need to bring your ID card and all the documents to the local labor and social security inspection brigade and fill out a complaint form. You can also directly call the 12333 Human Resources and Social Security hotline to ask what to do locally first, and then submit the materials online or offline.
The labor inspection department will take the initiative to find the unit to verify, forcing the unit to make up money, pay social security, and cooperate in determining seniority. If your unit doesn't cooperate, they will punish you directly, so you don't have to push yourself every day.
Step Four: The Last Step of Protection: Arbitration and Courts
If the previous methods are useless, or the company has been bankrupt and canceled long ago, you can go to labor arbitration or court.
Arbitration is also free. Apply to the local labor and personnel dispute arbitration committee;
If you are not satisfied with the arbitration result, go to court to sue;
If you have retired and are unable to make up social security contributions, you can ask your employer to compensate for the loss of pensions and medical insurance.
You don’t have to worry about the time limit. There is no saying that social security and seniority matters cannot be handled after a certain period of time. Even if you find out after retirement, you can still handle them.
4. The truth that must be remembered: Do not step into pitfalls when doing things in 2026
Based on the latest implementation situation, I would like to give you some of the most critical and practical reminders to prevent everyone from running and working in vain.
1. There is no national unified policy for checking the length of service, so it is more reliable to take the initiative yourself.
There is no talk about the issue of buying out seniority during the national unified census. You don’t have to wait or rely on it. You can find the problem yourself and handle it according to the process. This is the most reliable and fastest way.
2. Signing does not count. In these cases, the agreement is useless.
As long as any of the following situations occurs, the buyout agreement signed that year will not count, and you can still protect your rights:
Your employer forces you to sign or scares you into signing;
The money given is much less than the national regulations, which is obviously unfair;
The agreement states that you will give up social security and seniority, but the country does not recognize it;
The employer did not tell you the true policy and deliberately tricked you into signing it.
3. Even if the unit is gone or the name is changed, someone will still be responsible.
Unit restructuring and merger: Find the new unit you are taking over;
Company bankruptcy: contact the bankruptcy liquidation team;
Cancellation of the unit: Find the original boss and shareholders;
Old state-owned enterprises and collective enterprises: contact the superior authority.
4. The service details are different in each place, so call first to ask.
How to supplement social security and how to determine length of service, the details will be a little different in each city. Before doing anything, be sure to call 12333 to find out what you need to bring, where to go, and who to ask for help. This will save you a lot of unnecessary trips.
5. Don’t throw away old materials. The longer they last, the more valuable they will be.
Wage slips, work certificates, buyout agreements, copies of files, these old things at home, must not be thrown away as waste. These are the most critical evidence for your work. It will be very troublesome to replace them if they are lost.
5. Three little things you can do now without waiting or procrastinating
Don’t think it’s troublesome to protect your rights. Starting today, do the three simplest things first, and you will be able to straighten things out over time:
1. Take out your mobile phone and check your social security payment records to see if you have broken off social security or paid less;
2. Go through old boxes and cabinets at home, find out the salary slips, agreements, and work certificates from that year, and organize them;
3. Call 12333 and find out what city you are in and how to handle social security supplementary payment and length of service determination.
After doing these three little things, you will find that actually safeguarding your rights is not complicated at all. Everything is done according to the rules. As long as you have all the materials, you can get it done.
Many of my friends who bought out their seniority at that time are people who have dedicated most of their lives to the factory and the company. They work diligently and should not lose their legitimate rights and interests in vain because they do not understand the policies and regulations.
Buying out your seniority is never a one-and-done deal. The money you were underpaid, the social security you didn’t pay, and the seniority you missed are not old debts that cannot be recovered, but the protection that the state clearly stipulates and must give you. No matter how many years have passed, whether the company is still there or not, as long as you want to protect your rights and interests, there are channels, methods, and policy support.
There is no need for you to feel embarrassed or to think that you are looking for trouble. Getting back the treatment you deserve is a legitimate and legal matter. I hope that every friend who has experienced a buyout of service length can understand their rights and interests, get back the money they should get, make up for the social security that should be paid, and recognize the years of service that should be calculated, so that their later life will be more solid and secure.
Have you or a family member ever experienced a buyout? Did you encounter situations in which you received less compensation, failed to pay social security, or missed the calculation of your length of service? Do you think the most difficult thing when defending rights is finding old materials, asking about policies, or communicating with the unit? In your area, are there any simple and convenient ways to supplement social security payments and determine length of service? Welcome to share it and help more friends in need.
