Contractors on California public works must keep and submit 'certified payroll records' that document:

Explicación

Labor Code §1776(a) requires records showing, for each individual worker, the name, address, social security number, work classification, straight-time and overtime hours worked each day and week, and the actual per diem wages paid, verified under penalty of perjury. Crew or trade totals fail because the record is per worker per day, not per crew. Contract price, change orders and retention are accounting for the contract, not payroll for the workers. The awarding body's payment dates belong to the progress-payment record, not to the certified payroll.
