The short answer

With a regular schedule, the greenhouse horticulture collective labor agreement includes an overtime allowance of 35%; 50% applies to the eleventh working hour in a day. First determine which hours are overtime according to your schedule. An annual hours model and the student scheme have a different effect.

First determine which hours entitle you to allowance

The contract size and schedule are the starting point. Part-time work does not automatically rule out overtime allowance. The industry explanation makes an explicit distinction between a regular schedule and the annual hours model. In that annual hours model, additional hours initially arise; the settlement follows according to that arrangement. So do not enter those additional hours without checking as overtime to be paid immediately.

Split hours with different percentages

An hour that falls under the 50% rule does not count again as a separate overtime hour with 35%. Record normal hours each day and any eleventh hour. Calculate groups with different allowances separately and then add the amounts. The calculator calculates an entered number of hours; he does not independently derive the collective labor agreement entitlement from your total weekly hours.

This is how you check it

  1. Check whether you have a regular schedule or annual hours model.
  2. Split regular overtime and any eleventh hours in your timesheet.
  3. Confirm the conditions and only then copy the correct line into the calculator.
Practical example

Calculation example: four regular overtime hours and one eleventh hour at €16 gross. Four × €16 × 1.35 = €86.40; one × €16 × 1.50 = €24. Together €110.40 including basic salary. Do not add the eleventh hour again to the four other hours.

Questions about this CAO

Is 35% the total wage for the overtime hour?

No. It is an allowance on top of the basic salary. With an extra 35%, the total for that hour is 135%.

Do I get 35% plus 50% before the eleventh hour?

No. The same hour should not be counted twice. The industry explanation uses the 50% surcharge for that eleventh hour.

Can a part-time worker have overtime?

Yes. Check the agreed hours and schedule; Using only the general full-time limit may be incorrect.

Is every additional hour in the annual hours model immediately affordable?

No. That model has its own settlement moment and rules for plus and minus hours. Check this before calculating a surcharge.
