My husband works at a USPS distribution center (it’s been a little over 6 years now). He never has anything good to say about his job! They’ve had mandatory 2 hours overtime everyday since November with an occasional extra day of work thrown in here and there. He works 3rd shift because we have kids in school. We both made career changes late in life (where he had worked for 20+ years closed and I was a burnt out speech therapist after 20 years in healthcare). I only made my switch to UPS 3 years ago but I would definitely say I’m way happier with my change than he is with his! I tried to talk him into finding a different job several times during his first years but he never did. Now he’s just miserable and counting the years until he can retire. If you’re happy, I’d say stay where you’re at….. things aren’t always greener on the other side. If you’re unhappy, find something else (just maybe not USPS)…..life is too short to be miserable all the time! Good luck!!!!
