Secondary teachers on the other hand may have contracts ranging from 20 to 48 hours, which exceptionally may reach up to 60 hours per week. A teacher can also complement his or her teaching position with other functions in the public sector as long as he or she does not exceed 60 hours per week. Secondary teachers who additionally teach in a non-public school may exceed this maximum of teaching hours per week. Also, in a given school year, if the teacher is not able to have enough hours to complete a single teaching unit (20 hours or 40 hours), he or she can work a few hours in a supporting function (e.g. support teacher, pedagogical counsellor teacher, bibliographic counsellor teacher).
