Sick Leave During an Apprenticeship: Benefits, Waiting Days and Missed Classes — The 2026 Guide

You're 20, in the second year of your apprenticeship, taking home around €950 net a month — and one Monday morning in November, the flu keeps you in bed for eight days. The doctor hands you a sick note. You send it to your employer, email the training centre, and figure that's that.

It isn't. At the end of the month, your payslip shows €640 instead of €950. You look for the mistake, but there isn't one: there's a waiting period, a daily-benefit calculation that doesn't land in your account at the same time as your salary, and a collective agreement you've never once opened. And in January, your training centre informs you that the 21 hours of classes you missed will have to be made up before the exam.

Sick leave is one of the costliest blind spots in work-study programmes. Nobody mentions it when you sign, because nobody imagines falling ill. Here's how it really works in 2026, what you actually receive, and the three steps that make the difference between a month docked by 30% and an almost normal one.

The principle: an apprentice is an employee, with the same rights — and the same limits

That's the starting point, and it's more favourable than people think. Whether you're on an apprenticeship contract or a professionalisation contract, you hold an employment contract. You pay contributions, so you're covered by the general health insurance scheme just like an employee on a permanent contract.

In practical terms, a sick note prescribed by a doctor potentially triggers two separate payments, which must never be confused:

• Social security daily benefits (indemnités journalières, or IJ), paid by your CPAM (local health insurance fund), calculated on your gross pay over the previous three months.
• The employer top-up (also called "maintien de salaire", or salary continuation), paid by the company, provided for by the Labour Code and often improved by the collective agreement.

These two sources are neither triggered at the same moment nor subject to the same conditions. That's where the whole difficulty lies.

Eligibility conditions for daily benefits

To receive daily benefits for a sick leave of less than six months, the Assurance Maladie (ameli.fr) requires that, on the date the leave begins, you meet one of these two conditions:

• have worked at least 150 hours during the three calendar months (or 90 days) preceding the leave;
• or have paid contributions on earnings at least equal to 1,015 times the hourly SMIC (minimum wage) over the preceding six months.

For an apprentice working 35 hours a week, the 150-hour condition is met in roughly a month and a half. But watch out: time spent at the training centre counts as actual working time under an apprenticeship contract. This is the point that many non-specialist payroll managers get wrong. If any doubt arises, get it in writing: training time is treated as working time when establishing entitlement.

On the other hand, an apprentice who falls ill during the first few weeks of the contract — in October after a September start, say — may find themselves below the threshold if they have no declared summer job on record. Check your ameli account before panicking: hours from a student contract the previous summer count too.

The real calculation: what you receive, euro by euro

The daily benefit equals 50% of the basic daily wage, which is itself the average of your last three gross salaries divided by 91.25.

Take a concrete case: a 21-year-old apprentice, second year, gross monthly pay of €1,100.

Step	Calculation	Result
Basic daily wage	(1,100 × 3) ÷ 91.25	€36.16
Gross daily benefit	36.16 × 50%	€18.08
Net daily benefit (after CSG/CRDS ~6.7%)	18.08 − 1.21	≈ €16.87
8-day leave, 3 waiting days	16.87 × 5 days compensated	≈ €84

So over eight days of absence, the Assurance Maladie pays you around €84, while the net salary you lose over the same period is close to €250. That gap is exactly what the employer top-up is meant to cover — when it exists.

The three waiting days, and how to get around them

Social security never covers the first three days of a sick leave (article L. 323-1 of the Social Security Code). Two exceptions worth knowing:

• In the case of an uninterrupted extension of an initial sick leave, the waiting period applies only once.
• In the case of a recognised long-term condition (ALD), the waiting period applies only to the first leave linked to that condition over a three-year span.

The employer top-up has its own waiting period. The Labour Code (article D. 1226-1) provides for salary continuation from the 8th day of absence, subject to one year of service — a condition that in practice excludes virtually all first-year apprentices. This is where the collective agreement becomes decisive.

Your collective agreement is worth more than the Labour Code

This is the step 90% of apprentices skip, and it's the one that pays off most. Many sectors — metalworking, construction via the ETAM agreements, hospitality and catering, banking, IT (Syntec) — provide for salary continuation with no waiting period or with a service requirement reduced to three or six months, sometimes at 100% of net pay for 30 to 90 days.

How to check in five minutes:

1. Find your company's IDCC code: it appears at the top of your payslip, next to the applicable collective agreement.
2. Search for that number on Legifrance or on the Ministry of Labour website, under "conventions collectives".
3. Open the "maladie" (illness) or "absences pour maladie" chapter and read the length-of-service conditions.
4. If the agreement is more favourable than the Labour Code, it applies — automatically, with no need for you to negotiate.

A first-year apprentice at a company covered by the metalworking agreement may receive salary continuation from the first day of sick leave, where the Labour Code would give them nothing. The difference over a ten-day absence: roughly €300.

If your employer uses subrogation, it collects the daily benefits directly from the CPAM and pays you your usual salary: you barely notice anything. Always ask whether subrogation is in place — it's by far the most comfortable arrangement for your cash flow.

The 48 hours that decide everything

The deadline is short and the penalty is real: send the sections of your sick note within 48 hours, or the CPAM can cut your daily benefits by 50% for the period of delay (it will first send you a warning on the first lapse within a two-year window).

The procedure, in order:

• Sections 1 and 2 → your CPAM, unless the doctor has filed the note electronically (the majority of cases today — check your ameli account within 24 hours).
• Section 3 → your employer.
• A copy → your training centre or training provider, the same day. This is a contractual obligation in almost every training-centre code of conduct.

This triple submission is the classic sticking point: the apprentice notifies the company, forgets the training centre, and ends up with an "unjustified" absence appearing in their exam file. Keep a time-stamped record: an email with read receipt, or a photo of the section sent via work messaging. For longer absences, many apprentices keep their paperwork in a simple medical follow-up notebook, listing leave dates, submission dates and contacts — it seems excessive right up until the day a fund disputes a deadline.

Also remember to check your enrolment in the company health insurance scheme: it's mandatory for all employees, apprentices included, and many group policies provide additional compensation during sick leave. You'll only receive it if you ask, form in hand.

Missed classes: the real risk isn't the money

Financially, a short absence is manageable. Academically, it's another matter. Three consequences to anticipate.

1. Training hours still have to be completed

An apprenticeship contract requires a minimum volume of training hours at the training centre (at least 25% of the total contract duration for a diploma). Sick leave doesn't reduce that obligation: missed hours must be made up, one way or another — handouts, support sessions, online modules, sometimes evening classes.

Ask the training centre, in writing, as soon as you're back for:

• the materials and answer keys for the sessions you missed;
• the list of assessments to retake and their schedule;
• whether a partial attendance waiver is possible for modules you've already validated.

2. Continuous assessments (CCF)

In BTS programmes, vocational baccalaureates and professional qualifications, part of the exam grade comes from continuous assessments (CCF) carried out during the year. A justified absence from a CCF entitles you to a make-up session organised by the institution — but it isn't automatic: you have to request it, with a medical certificate, generally within eight days. After that deadline, the zero can stand.

3. The contract end date isn't pushed back

Contrary to a stubborn misconception, sick leave does not automatically extend an apprenticeship contract. An extension is possible in only two cases: failing the exam (extension of up to one year) or a recognised disability. A long illness may justify an adjustment, but it must take the form of a three-party amendment signed by you, the employer and the training centre, then filed with the OPCO. Nothing happens on its own.

For an absence of more than a week, the strategy that works is turning immobility into light revision: go back over your existing course notes rather than tackling a brand-new chapter. A pack of A5 index cards and a highlighter are enough to turn three afternoons of convalescence into a genuine head start on the syllabus, without any heavy cognitive effort.

Commuting accidents and occupational illness: a more protective regime

If you're injured on the journey between home and work, or between work and the training centre, this isn't ordinary sick leave: it's a commuting accident, falling under workplace accident and occupational illness legislation (AT/MP). The differences are significant:

	Ordinary illness	Workplace or commuting accident
Social security waiting period	3 days	None
Daily benefit rate	50% of daily wage	60% for the first 28 days, 80% thereafter
Medical costs	Standard reimbursement	Covered at 100% of the social security rate
Declaration	By you	By the employer within 48 hours

An accident occurring during classes at the training centre also falls under the AT/MP regime: the employer is the insurer, even if the accident happens on training premises. The INRS and the Assurance Maladie regularly remind people of this point, which is poorly understood by small businesses.

A useful reflex: always report an accident to your employer within 24 hours, however minor. A sprained wrist in the training centre car park that turns into a three-week absence six months later will only be properly compensated if it was reported in time. For manual trades, prevention remains the best lever: a pair of comfortable safety shoes in the right size prevents more absences than any amount of paperwork.

Can you be dismissed or have your contract terminated while on sick leave?

No, not on grounds of illness. Illness is not a valid reason for termination: that would be discrimination based on health status, prohibited under article L. 1132-1 of the Labour Code.

Important nuances for apprenticeships:

• During the first 45 days of practical training at the company (days actually worked, not calendar days), either party may terminate freely. Sick leave suspends that count: days of absence don't count towards the 45 days. A long absence therefore pushes back the end of that window, which works against you.
• After that period, termination requires a written agreement between both parties, gross misconduct, unfitness established by the occupational physician, force majeure, or exclusion from the training centre.
• Unfitness can only be declared by the occupational physician, never by the employer or by your own GP. And since the occupational health reform, the employer must look for redeployment before terminating on those grounds.

If you're under pressure ("come back or we end the contract"), the people to turn to, in order, are: the apprenticeship mediator at the relevant chamber (CCI, CMA, chamber of agriculture), free of charge and competent on this issue; then the labour inspectorate; and finally the industrial tribunal (conseil de prud'hommes).

The checklist to keep handy

• Day 0: consultation, sick note issued. Check that the doctor files it electronically.
• Within 48 hours: section 3 to the employer, copy to the training centre, sections 1 and 2 to the CPAM if there's no electronic filing.
• Day 2: ask the payroll department whether subrogation is in place and what the collective agreement provides for salary continuation (IDCC code in hand).
• Day 3: report the absence to your training centre's academic coordinator and request the materials from the sessions you missed.
• On your return: request make-up sessions for the CCF concerned in writing, and check the number of days deducted on your payslip.
• Absence of more than 30 days: a return-to-work medical examination with the occupational physician is mandatory, arranged by the employer. Your return to your post depends on it.
• Long absence: consider a three-party amendment with the training centre and employer to adjust the contract, filed with the OPCO.

A well-managed sick leave costs a few dozen euros and two emails. A badly managed one costs you a zero on a continuous assessment, daily benefits cut in half, and an argument with your employer. The difference lies entirely in the first 48 hours — and in having read, just once, the "illness" clause of your collective agreement.
