Not available days of teachers

[Yagmur Cerkez]

I want to give one day off to all teachers. But can we enter a constraint that lets certain teachers work the same days of the week and have the same days off? other than a teacher's not available times - because the data is too much. I want the software to assign certain teachers' off days randomly. For example, two teachers having an off day on Tuesdays and the other three having an off day on Wednesdays.

There are very many variants to do it, depending on what you intend, because I do not understand exactly:

1) Teacher(s) max days per week.

2) Add an activity with duration n_hours_per_day for each teacher, then:

2a) Activities same starting time

or

2b) Activities min/max simultaneous in selected time slots.

The second option might be helpful. Thank you very much.
