32 contractual hours per week (average on a 12 day roster) including 25% break time if my memory is correct.
In practise, these hours will be reduced due to lower flight activity hence lower controlling needs.
French law imposes a minimum of 11 hours between two work days as a general rule and ATCs will have that or more. No administrative duty to my knowledge
Satellite Man : underpaid, lol.
Salary for an area controller or for a tower controller at a large airport will be 5k-8k (increase from 5 to 8k€, net, before income tax over the course of one's career)
