Here is some of the specifics on my situation.
We preform year around, so I would always be working on a show (5 of the six shows) - so I would never not be on an equity contract (So pension is not an issue.) They want to include me on their health insurance (so I would be double insured). Extra duties will include calendaring for show specific situations, supervising staff, hiring/firing staff (ASM, PA, Interns, other SMs), supplying SMs for readings, events, etc, etc, etc. There would be some additional staff requirements such as staff meetings, department head meetings, etc.
What I am looking for is to see if anyone has had a specific situation or know someone who has - what sort of salary bump should I ask for? What should I negotiate into the contract? What should I be aware of?
