Employment contract

Part-time work can be imposed by the employer, but it can also be tempting to do so when you don’t have enough time to reconcile professional and personal life.


However, the fear of losing part of their income and social benefits often deters employees. But what is it really? How to calculate the possible loss of salary? Here are some tips.

Who are part-time workers?

Part-time work can be imposed by the employer, as is the case in many sectors such as personal and business services (maintenance agent, security agent, etc.), early childhood, health/social (caregiver, nurse, etc.), hotels and restaurants (waiter, cook, etc.) or even commerce (salesperson, sales consultant)… But employees can also opt for this mode of work on their own initiative and with the agreement of the employer, in order to have time for their children for example, to limit expensive journeys, or because they do not “need” to be on time financially full…

A part-time contract drawn up by the employer will stipulate the expected salary as soon as it is signed. However, when one decides to go part-time, as is the case with many parents who have just had children and/or who want to take parental leave, it is difficult to estimate the real impact on remuneration. . Before reducing your working time, it is therefore recommended to do this calculation to avoid unpleasant surprises on the pay slip!

Note that the transition to part-time is subject to the agreement of the employer, except in the case of parental leave. The company cannot refuse parental leave, part-time or full-time, to its employees.

Calculate your working time

A 35-hour employee is paid 151.67 hours/month, i.e. 35 hours x 52 weeks/12 months. A part-time employee working 28 hours per week (at 80%) will be paid 28 x 52 / 12 = 121.33 hours per month. To obtain the amount of the monthly salary, you must then multiply the number of hours by the hourly rate.

It should be noted that any hour worked beyond the working time indicated on the contract is considered as an “additional” hour (the equivalent of overtime for full-time employees) and must be paid to the employee. Additional hours are limited to 1/10 of weekly or monthly working time. However, if a convention or agreement provides for it, they can be increased to 1/3 of the weekly or monthly working time.

Know your net salary

“To estimate your part-time salary, you have to take your monthly or annual gross and multiply it by 80% or the percentage of work time envisaged” explains Lucie Dalibot, HR manager at Regionsjob. But how do you know your part-time net monthly salary and know what exact salary you will have at the end of the month? To go from gross salary to net salary, an average of 23% must be deducted: – 21/22% for ETAMs and – 23/24% for executives. For example: if you earn 1800 euros gross per month, you will receive 1800 – (1800 x 23/100) or 1386 euros.

Then, you must take into account the other deductions made each month on your payslip depending on your time of presence.

What impact on your payroll?

  1. Paid vacation

Paid leave is not affected. The part-time employee is entitled, like the others, to 25 days of leave per year.

2. RTTs

Usually, the calculation of the RTT varies according to the weekly schedule of the employees. In the case of part-time work, they are prorated based on the employee’s attendance time. But to find out how RTT is calculated in your company, refer to the collective agreement by asking your HR department. Example: in many companies, an employee benefits from 0.80 RTT per month.

3. Employee participation

On this point, everything depends on the company agreement. The participation is calculated according to the distribution: either by uniform distribution between each employee, or in proportion of the wages, or in proportion of the time of presence in the company, or by combining the 3 criteria above. In some companies, 60% of the amount of the participation is linked to attendance time, so in the event of part-time work, the amount of this will be impacted.

4. Mutual insurance and meal vouchers

To find out the real impact of your part-time work on your salary, you must also take into account the deduction of any company mutual insurance if you benefit from it, but also that of meal vouchers if you are entitled to it. “For the mutual, there is no difference whether you are full-time or part-time, the contribution is the same” explains Lucie Dalibot of RegionsJob. However, “for half a day or 1 day of absence, 1 restaurant ticket is deducted from you” she specifies. The total amount of the “employee share” in restaurant tickets will therefore be impacted.

If you’ve decided to go part-time, don’t forget that you can negotiate with your employer to keep some of your benefits!
