Well based on 48 hours/week:
- Year 1 ($18.75): $51K
- Year 2 ($19.50): $53K
- Year 3 ($21.00): $57K
- Year 4 ($25.00): $67K
- Year 5 ($36.50): $99K
That Year 5 rate is a very conservative (low) estimate of what the top rate will be in 2019. It could be about $37.50 to $38.00
Also consider you won't be paying weekly/monthly premiums for your health insurance. There will be monthly union dues (and an initiation fee).
