Officers Forced/Ordered in

In the near future my union will be involved in negotiations. During the past 6 months Officers/Sergeants have been forced/ordered in to work a patrol, supervisor shift. This has been a new occurrence for our department. and we currently have no contract language pertaining to this topic (only rules& regs).

I am looking for language/compensation that other departments utilize when an Officer/Sergeant is forced to stay or is ordered in. We are looking for language that pertains to OT shifts that cannot be filled and not for emergency circumstances, i.e. nature disasters.

Please PM me with any answer(s).

Thanks.
