If you apply my union contract to these employees:
40hrs @ 13/h = 520/wk
20hrs @ 19.50 = 390/wk
(My contract is actually overtime after 35hrs, but most are 40, so I'll use that.)
520 + 390 = $910/wk ×52wks = $47,320/yr
12hr day entitles me to:
Breakfast @ $12. × 6= $72
Lunch @ $18 × 6 = $108
Supper @ $26 ×6 = $156
72 + 108 + 156 = $481/wk (tax free)
I would say that 250 miles for a week would be a conservative estimate for mileage for a 6 day work week.
.58 × 250 = $145/wk (tax free)
481 + 145 = $626/wk (tax free)
910 + 626 = $ 1536/wk or $79,872/year, with only $47,320 being taxable.
On top of that, 20 sick days, 5 family illness days, 4 appointment days and 5 wks vacation, benefits (drugs, dental, LTD/STD, employee assistance program, health spending account, and a defined benefit pension plan [based on my best 5 years, not my contributions]), and all my work expenses paid for, etc..
Don't be fooled by a $13/h slum job compared with a Union position.
I don't know their contract so it's hard to judge, but I'll just put this out there. I don't make near that amount because I don't work that much. I make way more per hour but only work about an average of 10hrs/month or so of overtime, and only get maybe 10 meals/year, but perks can add up quickly.
