Working on a fixed-term contract after 50 or in retirement: a practical guide

What a fixed-term contract means for someone over 50

In France, a fixed-term contract (contrat à durée déterminée, or CDD) is an employment contract whose end is settled when it is signed: either a specific date, or the end of a task or of someone else’s absence. There is no separate “senior CDD” in ordinary employment law. The same rules apply to every employee, whatever their age. What differs is the way people use the contract.

For a jobseeker over 50, a CDD can act as a stepping stone towards a permanent post. For a retiree, it offers a way back into a working rhythm for a few weeks or months, after which they are free again. Either way, the employer’s duties are identical: a written contract, pay at least equal to that of a permanent employee with the same qualification, and respect for the applicable collective agreement.

When is an employer allowed to use a CDD?

A CDD cannot be used to fill a post that belongs to the normal, permanent activity of the business. French law lists the situations in which it is allowed. The most common are:

• replacing an absent employee (leave, illness, training);
• a temporary increase in activity, such as a seasonal rush;
• covering the gap until a newly hired permanent employee arrives;
• seasonal work, or certain “customary” jobs in sectors that the rules name.

The reason must be written into the contract. If it does not match reality, for instance a replacement that does not exist, it is worth asking for an explanation and perhaps seeking specialist advice. The stated reason also determines how long the contract may last.

Length, renewal and trial period: the benchmarks

As a general rule in France, a CDD may not exceed eighteen months, renewals included. Some situations allow a shorter limit, for example nine months for urgent safety work or while waiting for a permanent hire to start, and some a longer one, up to twenty-four months in specific cases. A collective agreement can also set different rules, so check the one that covers the employer.

A contract may contain a renewal clause; without one, an extension needs a written amendment. If a trial period is planned, it has to be in writing and stays proportionate to the length of the contract. A CDD can also be signed without a fixed end date, typically to cover an absent person, in which case a minimum duration is stated.

These are general benchmarks only. The exact limits depend on the reason for the contract, the sector and the date of signature.

Pay: salary, end-of-contract bonus and holiday entitlement

An employee on a CDD earns the same hourly rate as a permanent colleague in a comparable post. When the contract ends, they are normally entitled to an end-of-contract allowance, often nicknamed the “precarity bonus”, worked out as a percentage of total gross pay. It is not payable in some cases, for example when the employee turns down a permanent contract on the same job, or in seasonal work, unless a collective agreement says otherwise.

Paid leave builds up during the contract, and anything not taken is paid out as a compensatory allowance. To find out what you will really receive, ask the employer for a worked example and read your first payslip carefully: that is the easiest way to spot a mistake while it is still simple to put right.

A CDD and your pension: how the two fit together

Taking up salaried work while drawing a French pension falls under the “employment-retirement combination” (cumul emploi-retraite). To qualify, you must already have claimed all your basic and supplementary pensions. The combination is “full”, meaning there is no income ceiling, once you reach the age for a full-rate pension, or the legal retirement age together with the required insurance record. In other cases it is capped, and the pension can be reduced if you go over the limit.

Two points deserve attention. First, a six-month waiting period normally applies if you go back to your last employer, for recent retirements. Second, periods worked since 2023 can earn a second, limited pension. Changes have been announced for pensions starting from 2027, so check with the French pension insurer (Assurance retraite) before making any decision.

Finding an assignment: the routes that work

Fixed-term vacancies circulate through several channels. Employment agencies often offer short contracts, including CDDs, for clients who need cover. Specialist job boards, and the recruitment teams of local authorities, hospitals, schools and charities, also post temporary needs.

Word of mouth remains effective: a former colleague, a former employer or a charity where you volunteer may know of a need before it is advertised. As a retiree, it helps to state your availability clearly (periods, days, distance you will travel) and to describe your experience in one precise trade, rather than staying vague. One targeted application is worth more than ten identical ones.

Reading the contract before signing: a checklist

A French CDD must be in writing and handed to the employee within two working days of starting work. Before you sign, check at least the following:

1. the reason for the contract and, where relevant, the name of the person being replaced;
2. the start and end dates, or the minimum duration;
3. the job grade, the pay and the weekly hours;
4. the workplace and working hours;
5. the collective agreement that applies and any trial period;
6. the reference to the end-of-contract allowance.

A contract with nothing in writing, or signed late, can be reclassified as permanent. If in doubt, a simple question to the employer or to a legal information service saves a lot of trouble later.

Things to watch: tiredness, travel and back-to-back contracts

A CDD often means slotting into a team’s rhythm very quickly. Depending on the job, standing all day, lifting, irregular shifts or the commute can weigh more heavily than you expect after several years away from work. Before accepting, it is reasonable to ask for the detail of the tasks and the rota, and to see your doctor if you have any concern.

Chaining contracts also calls for caution. A waiting period may apply before a new CDD can be signed for the same post. Income from short contracts is irregular as well, so plan a budget that does not depend on an extension. Finally, telling your pension fund about the work within the required time is an obligation, not an optional formality.

A worked example: three months of cover after retirement

For illustration only, picture a former payroll manager, retired for a year, who is approached by a small firm whose accountant is going on maternity leave. The assignment is a three-month replacement CDD, part-time, with pay in line with the post.

Before signing, she checks the reason and the dates, asks for the collective agreement, and then tells her pension fund that she is working again. When the contract ends she receives her final salary, the end-of-contract allowance and a payment for untaken leave. If the firm offers an extension, she first looks at what it would do to her combined income before replying. This example is not a promise: every case depends on the contract, the pension and the employer.
