I did back in Sept. 2012.
I used to work on the inside (money processing) for an armored company. It was year of events that eventually led me to quitting. In the fall of 2011, we lose one our biggest customers but everything was still mostly cool. At the beginning of 2012, my manager and another worker get fired over missing money. A handful of people knew about it but I guess they couldn't fire everybody. shyt got crazy for a little bit with the OT but it worked it's way down.
Fast forward to May 2012 and we gain a "new" old customer which in brings in more work than we can handle. Hell, our whole region did a horrible job of planning for the new work. My hours got even worse. I went from 40-42 hrs/wk to like 60. What good is a lot of OT if I'm too tired to do shyt.

Finally by September (which is when my department finally hired a manager - that's right, my area took 8 mos. to officially hire a manager

), shyt was affecting me on a personal level so I said fukk it.
shyt was hard though as it took me 9 mos. to find something permanent. I did do a couple of temp jobs along the way but that shyt is
temporary. I applied for mass jobs but got the runaround a lot.
The shyt I hated the most is when a job talks about entry-level type but then asks for all this experience. A lot of jobs out here ain't willing to train for nothing.
