It's unclear from the post....are you ACTUALLY working on an Equity contract, or just a company that likes to use it for reference? That makes a big difference. If it's an Equity contract, a call to the business rep may be in order. If it's guidelines only (like, I know many college campuses that try to abide by them anyway), that's a little more flexible. Also, an actor (or stage manager) cannot just vote away/sign away any rights, no matter the contract. And any vote that is officially allowed needs to include the stage manager too. (They often think actors only can decide that.)
Now, if we go over a break by 1 or 2 minutes, that's something different, and then I might make it a 12 or 15 minute break after. But outright scheduling without proper AEA rulings (no more than 5 hours in a row, correct span of day, etc), that is not something to allow on a true Equity contract.
