constrain: 2 teachers not to teach on the same time

new user here, thank you for your work

I need 2 teachers not to teach on the same time.

The solution I found is to assign on all their activities a virtual co-teacher, is this the optimal way? or i miss something?

Welcome and thank you!

I think a constraint activities not overlapping is the best option.
