I'll say up front, I've been working for [redacted] since early September, and it has its ups and downs.
It pays well, but it is unlike any Stage Management work you've ever done.
From what I've seen working here, there are twenty or so supervisors with various titles, and when you have any notes or problems during rehearsal, it takes several supervisors and many different channels to get a change or note done or approved.
Also, many times, corporate gigs come with extra tasks. For example, I have to edit all of my actors on the timecard system they use here, which has a steep learning curve.
Also, you'll find that you have a lot of limits. There are many things that I am qualified to do, but I'm not allowed to here.
For example, I'm IATSE certified to run a union house, and I've worked as a TD in a union rental, but if I need to so much as screw something in, I have to call the right people and notify the correct supervisors.
It can be very frustrating.
On the plus side, corporate gigs come with rules that make it rather cushy. For example, I can only work some many hours a day, so if I don't get my report sent out, or my timecard edits done, too bad. And I always have certain breaks and a set schedule.
The best thing about corporate is that your time off is your time off. I'm not even supposed to check emails unless I'm clocked in.
I like the people and the pay, but it's very tough to put everything aside to do this kind of work.
Most corporate places simply post their SM work on their regular employment websites.
