Did I REALLY sign up for this??

Time to look for a 2nd job.  Today is the THIRD shift in a row that I have been put "on call". Which basically means that I have to be available to come into work should they need me for the whole 12 hours, thus I can travel no farther than 30 minutes from my home b/c I have to be there w/in 30 minutes or so if they decide they need me.  And while I understand low census I still don't think it's fair that I've been the one to have to take call for my last 3 scheduled shifts, I mean I'm thinking they should be switching this around & not just putting ME on call.  I know it's a Saturday & all but I think I'm going to send my boss a little text.  I mean this is ridiculous, I've worked ONE shift this week.  Not a happy camper.  Unfortunately b/c this is such a small, rural hospital there is nowhere to float to if your floor has too many techs & not enough patients.  Therefore I started applying for jobs at the hospital where I do my clinic...
