Erik,

Let's take your numbers:

UPS pay: $28/hr.
UPS Benefits:$11.2/hr
UPS pay total: $39.2/hr
UPS overtime pay: $42/hr

Number of hours/yr = 2080

Overtime hours/yr = 260 (5hrs./week)

Base pay with benefits = $81,536
Overtime pay = $10,920
Total pay = $92,456

5 hrs. of overtime is being conservative. Most of those guys work 10 or more hours of overtime.
