Besides the advice in the other thread . . . a question might be asked are there aspects of this job you can transform into an specific job in the industry.
Production management? General Management? Casting? (I know a SM who has made a fantastic career in casting for film, television and theatre.) Theatre Education?
But if really want to make a nice break with career - I can't say enough about temping to get your foot in the door - employers get to try you out - and once they see all your stage management skills in action, it often leads to a firm job offer (I temped in 5 different industries - from Aerospace, Health Care, Computers . . . and all of them lead to full-time job offers . . . of course, theatre, like the bad drug it is, kept me coming back.
