50 or 100 employees: must your company hold social elections in 2028?

50 or 100 employees: must your company hold social elections in 2028?

It is the first question any company asks: "are we concerned?" The answer comes down to two thresholds, 50 and 100 workers, but the real trap is not the threshold itself: it is how you count the headcount. Here is how the calculation works, and a decision tree to settle your case.

The two thresholds

The basic rule is simple:

  • From 50 workers, the company must hold elections for a Committee for Prevention and Protection at Work (CPPW).
  • From 100 workers, it must additionally hold elections for a Works Council (WC).

So a company of 120 people has two votes (WC + CPPW); a company of 70 has just one (CPPW); a company of 40 has none.

But those figures, 50 and 100, are not read off today's org chart. They depend on a precise calculation.

The real issue: how you count

Headcount is not measured by the number of people present on a Monday morning. It is calculated on an average employment over a reference period, in equivalents, across all contract types. Three elements count, and each can tip the result:

  • All contracts: permanent, fixed-term, replacement contracts, everything enters the calculation, not just the "permanent" staff.
  • Part-time: part-time workers count, under the applicable conversion rules.
  • Temp workers: temp workers made available are counted in the user company's headcount, following the reference-period rules. A company that relies heavily on temp work can cross a threshold it thought it avoided.

The classic mistake: "we're 46 on permanent contracts, we're not concerned." Once fixed-term contracts, part-timers and temp workers are properly counted over the reference period, that same company can exceed 50, and owe a CPPW.

An often-forgotten point: the threshold is counted per TBU

The calculation is not done per company, but per technical business unit (TBU). One company can contain several TBUs; several companies can form only one. It is the TBU that triggers (or not) the obligation. For that split, read What is a "technical business unit" (TBU)? Explained with real examples.

The decision tree: must you hold elections in 2028?

Follow the steps, per TBU:

  1. Calculate the average headcount over the reference period, including fixed-term, part-time and temp workers (not just the permanent staff present today).
  2. Under 50? → No social elections. Representation, if any, goes through the union delegation.
  3. Between 50 and 99? → You must hold elections for the CPPW.
  4. 100 or more? → You must hold elections for the CPPW and the Works Council.

And in any case where you are near a threshold: do the calculation early, because it governs the whole rest of the procedure, which starts on day X-60 (late 2027).

And below 50?

Below the threshold of 50, no WC or CPPW, so no social elections. But that does not mean no representation: the union delegation, set up under sector collective agreements, may exist and take over certain tasks. The elections threshold and the union-delegation threshold are two distinct things.

In short

Two thresholds: 50 for the CPPW, 100 to add the Works Council, counted per TBU. But everything turns on the headcount calculation: average employment over a reference period, across all contract types, temp workers and part-timers included. Many companies believe they are out of scope and discover the opposite once the calculation is done. Do it early.
