Should I work at Labor Ready or not work Labor Ready?

Right now, I contemplating working at Labor Ready. I have little luck getting a full-time job and the part-time job that I had which barely paid me at all, but at least was a job is now gone. Now, I am seriously thinking about working Labor Ready because I just want some extra money and not deplete my savings any more. Looking for a job full-time has yielded a lot of interviews and no jobs. I still want to look for a full-time job but I really not interested in depleting my savings any more even though I have at least $45,000 in liquid assets. And I am tired of having a huge gap on my resume. Is it better for me to work at Labor Ready and look for a job part-time or keeping on depleting my savings because a possible full-time job is coming up? My gut feeling is better to work at Labor Ready which does not a permanent committment and wait for full-time job than try to dedicate myself to permanent part-time job that is not in my field?
