Heatwave and work-study in 2026: your rights when the CFA closes

Summer 2026 is starting on a reality that many apprentices discover during the first heatwave: between the CFA (training centre) and the company, who is responsible when it is 38 °C? And who pays when an employer decides to "make up" the hours because the CFA closed for an orange alert? The law is more protective than you might think — provided you know it.

In short: since the decree of 8 April 2026 and the recognition of heatwaves as a cause of work stoppage, the apprentice benefits from several concrete protections — the right to cool water, breaks from 30 °C, a shaded area, refusal of "make-up" hours when the CFA closes, and possible compensation through the bad-weather unemployment scheme in construction. Any salary deduction or sanction for absence linked to a heatwave can be challenged before the labour inspectorate.

What does the law say when the CFA closes for a heatwave?

The first reflex to keep in mind: CFA closure does not mean exemption from going to the company. DREETS Nouvelle-Aquitaine recalled this in a note from November 2025: when the training establishment closes exceptionally (orange or red Météo-France alert), the apprentice is supposed to go to their company, unless it is materially impossible (public transport stopped, the company itself closed, employers more than an hour away with no solution).

"Making up the hours of CFA closure because of a heatwave has no legal basis. Making a wage deduction exposes the employer to litigation risk." — DREETS Nouvelle-Aquitaine, FAQ "What to do during a heatwave" (2025)

In practice, if your CFA closes on Tuesday because of an orange alert and your employer asks you to come on Saturday to make up: refuse. Note the request in writing (email, SMS) and alert your CFA — most of them have received an explicit instruction from the education authorities.

The employer's concrete obligations in case of intense heat

Article L. 4121-1 of the French Labour Code imposes a general safety obligation on the employer that applies fully to apprentices, whether adults or minors. In practice, from 30 °C (or 28 °C outdoors and in construction), the employer must:

• Provide cool drinking water (maximum temperature 15 °C recommended by INRS), in unlimited quantity;
• Set up a shaded or air-conditioned rest area, accessible without hierarchical authorisation;
• Grant breaks every 1h30 in case of strenuous or outdoor work;
• Adjust working hours: early start, late afternoon finish, avoiding the hottest hours (12 pm-4 pm);
• Provide suitable PPE: cap, light clothing, sunglasses, SPF 50 sunscreen for fully exposed positions;
• Reduce the pace or prohibit isolated work as soon as an orange alert is triggered.

Article R. 4534-3 (outdoor work) specifies that these obligations apply to all employees on the worksite, apprentices included, with no exemption possible. For minor apprentices, the Labour Code provides complementary rules (prohibition of night work, overtime) which, in case of heatwave, actually favour the adjustment of working hours.

Construction apprentice: bad-weather unemployment can compensate you

If you work in the building or civil engineering sector, a lever exists: bad-weather unemployment, managed by CNETP for construction. Until 2024, heatwaves did not entitle to compensation. This is no longer the case since the 2024 extension, tightened by the decree of 8 April 2026 which sets stricter rules to prevent abuse.

To be compensated as a construction apprentice, four cumulative conditions must be met:

1. An orange or red alert from Météo-France (a yellow alert is not enough, even at 35 °C outside);
2. Have completed at least 200 hours of work over the last two months in a construction company;
3. The employer must declare the stoppage within 120 hours (5 days) from the start of the stoppage;
4. A reimbursement form must be sent within one month of the resumption, otherwise the claim is time-barred.

The compensation amounts to 75% of the gross hourly wage, capped at 9 hours per day, 45 hours per week and 55 compensated days per year. The CIBTP France network confirmed as early as 26 May 2026 the eligibility of heatwave-related stoppages, due to an exceptional and early heat episode in western France.

For an apprentice in a vocational baccalauréat or BTS in construction, a compensated day often represents between €70 and €110 gross, versus zero in case of standard sick leave. This is a lever to know about.

Penalties faced by companies that do not play by the rules

The employer that ignores its heat obligations faces a cascade of risks — and it is important for the apprentice to know them in order to assert their rights without pressure:

• Formal notice from the labour inspectorate, then administrative fine of up to €10,000 per employee concerned (€20,000 in case of repeat offence);
• Employment tribunal litigation for failure to protect health;
• Recognition of inexcusable negligence in case of a work accident (heat stroke, fainting, dehydration);
• Specific criminal liability for exposing a minor apprentice to a danger (articles 223-6 and 222-19 of the French Penal Code);
• Civil liability of the company for bodily injury suffered.

For construction apprentices, these obligations are detailed in our guide work-study in construction: jobs and training 2026 — the sector most exposed to heatwave stoppages every summer.

What to do in practice if your rights are not respected?

If your employer asks you to make up hours, refuses a hydration break, or maintains a dangerous activity in intense heat, here is the procedure to follow — in order, without rushing:

1. Talk to the apprenticeship tutor first: it is their role to adjust the workstation, which is also what article R. 6223-22 of the Labour Code provides. If they do not move on, go to the next step.
2. Contact the CFA by email (copying the pedagogical coordinator): most CFAs have had a "heat alert" protocol since 2024 and can alert the DREETS of their region.
3. Contact the company's occupational doctor: they have the power to adjust or suspend your workstation. The alert is strictly confidential — no sanction possible.
4. Contact the labour inspectorate via your regional DREETS (e.g. auvergne-rhone-alpes.dreets.gouv.fr). You can do so anonymously.
5. Contact the CSE, or failing that, a staff representative: they have a right to alert and to withdraw regarding working conditions.

In case of emergency (heat stroke, a colleague fainting), the 15 (SAMU) obviously takes priority over any administrative procedure.

A few reflexes to keep in mind this summer

• Check the Météo-France alert every morning before leaving: the site vigilance.meteofrance.fr is the reference, and it is the only one that opens entitlements (orange or red only).
• Hydrate before you feel thirsty: an apprentice outdoors loses up to 1.5 L of water per hour at 35 °C.
• Keep a temperature log on your worksite or workshop: it may serve as evidence in case of litigation.
• Keep a written record of any contentious instruction (email, SMS, written message): in case of dispute, it is the number one piece of evidence.
• Mobilise your work-study rights even in case of CFA closure: your salary simulator integrates weather-related absences in the salary maintenance calculation, and our apprentice contract rights page summarises your protections.

For apprentices starting in September 2026, keep in mind that a heatwave is not a "bonus break": it is a regulated occupational risk, and your employer has the obligation to protect you. If that is not the case, speak up — the law is on your side.
