I was a UPS seasonal for many years. Worked 6 months per year at UPS, did side jobs and UE pay during the other 6 (or went on vacation in a warm weather state!).
No benefits when you are seasonal though.
FedEx offered me a permanent PT courier job. Started around $15.53 an hour. Worked approximately 20-24 hours weekly and got benefits. Take home pay after benefit deduction was around $210. Got a 3% raise, but with benefit deduction increase my raise only amounted to an extra $1.98 take home a week!
UPS called me back to drive seasonal. I said I needed a permanent position.
They offered me a job unloading trucks in the evening....$9.50 an hour. 15 hours per week.
No benefits for 12 months though. Obamacare til then I guess.
Thing is....since I can drive, UPS uses me for air delivery (11.50 per hour) or filling in on a route at $16.10...soon to go up.
All said and done I work about 25 hours per week and bring home $290. During peak and the summer months I take home about $600 a week.
So it is working out for me money wise.
However....the work at Fed Ex is like a vacation compared to UPS. You bust your ass at UPS like no job I have ever had!
In 3 years I can probably bid on a FT driving job if I want to bust my ass 9-10 hours a day, five days a week.
