My employer has posted the entire team a message explaining that "We will be needing everyone to complete a minimal of 8 hours OT per week" for the next few weeks. On the posted sheet, it says nothing about being manditory. However the supervisors are informing everyone it is manitory and if not completed, "unknown" consequences may occur. Many people on the team simply cannot complete the required hours, I being one as my college schedule revolves around work. Can they terminate if this "manditory" overtime is not completed? Thanks.

Yes, they can. Mandatory overtime is legal unless you have a valid and enforceable contract saying that it is not.

Ok, well in the handbook we recieved upon hiring, there is no mention of possible manditory overtime. Is this automatically implied that there can be manditory OT, or does it need to be in writing prior to the mandate?

No, there does not have to be a written policy for it to be legal for them to require it. There is no possible way they can have a policy for every eventuality that might come up.

The law does not require that they have written policies at all. Nothing in the law says that they cannot do something unless they have a written policy that says they can.

I say again, unless you have a valid contract that says they CANNOT require you to work overtime, they can. Whether it says so in the handbook or not.

Well I guess that takes care of that. Thanks.
