considering corrections again

I worked at a local jail for just over a year about 3 years ago. I was let go for "budget cuts" technically, but was on probation at the time for a lot of mistakes I made during the last few months there at my yearly review. Although you were supposed to be under a preceptor for the first year, she pretty much let me go on my own after the first month or so and thinking back, I don't think she did the best job training me. I didn't like it much there as it was usually very stressful and I always left with a headache. For a little over the past 3 years I've been at an assisting living facility and it is usually fairly laid-back as far as emergencies, ect. but it is also stressful at times due to management and hours getting cut whenever the census gets low and the call-offs and turnover of the aides. The benefits aren't that good either and they don't give raises, just "bonuses" twice a year that usually don't even cover a weeks wages.

Anyway, I noticed the local jail is hiring for per diem positions right now and I thought I'd apply for the heck of it to see if I could maybe work a day every other other weekend as I currently work 10 out of every 14 days. To my surprise the recruiter called and left a message, but I'm debating on whether to call back or not? It is a different company that you would work for now, but I'm sure the jail is run pretty much the same. Maybe a different shift wouldn't be as bad (I worked 2nd before), but I would think there would be some training and I don't have that much time off now to get a break from my full time job. But I do need the money as I recently got a notice the city is making me fix my sidewalk and I basically live paycheck-to-patcheck and can't afford it at the moment. What do you guys think, worth another shot and at least call and see what they say?
