2 consecutive real days?

[Benahmed Abdelkrim]

Hello!
Can this constraint be generalized? A teacher works a maximum of n consecutive days. The variable n can take the value 2 or 3 (with the exception AMAM for n=3)?

That's not exactly what I meant; perhaps I didn't express myself clearly. I wanted to know if it's possible to allow teachers a rest period the following morning after a full day of work (morning + afternoon).

I think it is possible: for each three consecutive days, teachers work only two. Use teachers occupy max 2 sets of time slots from 3.

Oh ... yes!, that's right! I wonder why I didn't think of that constraint? Thank you, dear Liviu!.
