I am in the same boat as we speak, with producer in a tiff because I haven't dedicated a full 40 hr week to the reading PRIOR to first rehearsal. And altho I have already but in a good 30 hours of work on the phone, in meetings,etc, let alone breaking down the script, picking up and dropping off scripts and scores, and solving all kinds of scheduling issues they forgot to track during auditions and figuring out how to relay some props and furniture the venue doesn't have. Overtime? Don't even think about it. Not included in the rules, so not even under consideration.
We really need to revisit the staged reading guidelines - not even counting that the paperwork still reflects those living in the 5 boroughs rather than being an inclusive national list. Protections aren't a part of the deal.
I do understand we take these as ways to meet/work w folks, to fill in short gigs in the gaps etc, but holy cow.
