Yup. I've done it before and I'd do it again if need be. As long as, like someone mentioned, there wasn't a "non-compete" issue.
I've worked for Lifetouch while learning (way back in the beginning of my photo career... as if that was SOOOOO so long ago.

), and I was allowed to continue doing what I do, as long as I wasn't competing against them for school contracts... which I was not.
And I have worked for... may STILL work for after the move... The American Wedding Group (The Pros), who have ZERO non-compete anything. I can shoot weddings with them... I can shoot my own weddings.. doesn't matter. As long as I don't tell my Pros clients my last name or give them info about my own ventures, I'm good.
There's a studio in Nashville that I was going to apply to work for doing non-photography things (Just to get my foot in the door), but they don't want their administrative staff to be photographers... at the very least they don't want them to be planning on going into wedding photography ventures of their own/already have a wedding photography business.
Not that I do that on my own at the moment, I'm not really sure HOW I would feel about doing that later on down the line, so I didn't want to accept a job that I would have to quit sooner than later just because my focus in photography expanded or shifted.
PLUS... I dunno if I'm still shooting with Pros or not. Cause Mama needs money, especially after the move, and God only knows if those gigs will make or break our financial situation, so I don't want to limit myself. Although, the goal is to work more often with local photographers assisting and second shooting than it is to work most often with the Pros. We'll see.
BUT ENOUGH ABOUT ME...
Back to you...
YES. I would do it. For the reasons you listed. It would give you a chance to improve YOURSELF... and the company. As long as it doesn't interfere with your other plans, I say go for it. :sillysmi:
