In 2008 I was disqualified due to an accident during my 30 day Probation period. I was sent back inside and allowed to work Saturday Air which I've been doing since May 2008. I signed the list last month and was told today it's my turn again, and to report to orientation next Monday, 2/13. My dilema: I have a full time job I'm satisfied with. I work for a major retailer in a Distribution Center. Decent job, decent pay and best of all I work Monday through Friday 7am to 3pm with minimal overtime. Been there over 2 years and would absolutely hate to leave with 4 days notice. In 2008, I was told I was consistently 1 hour paid over and would likely be extended. With a little more effort I think I would have made it. Between my full time job and UPS (including working Saturday Air at Air Driver top rate) I made 57k last year. I don't think I'll ever get the opportunity to make 70 to 80k a year anywhere else. I'm 36 years old and have 2 daughters. I'm completely torn. What would you do? What options should I consider?
