Are you being paid this rate?
Add your hourly wage to what your employer pays into health, pension and other plans for you, and compare it with $49.23. Plan payments only count if the money goes into the plan; your pay stub won't show them, but plan statements will. The training amount goes to the California Apprenticeship Council or an apprenticeship program, not to you. Check a week of pay.
Contractors on most public works jobs file certified payroll with the state, and anyone can look it up in DIR's CPR public search. If your total comes up short, you can file a public works complaint with the California Labor Commissioner.
