Legal Question in Employment Law in California

Your employer must pay you on regularly scheduled pay days. All wages for most non-exempt employees in California must be paid twice during each calendar month, on days designated in advance by the employer as the regular paydays. Labor performed between the 1st and 15th days, inclusive, of any calendar month must be paid for between the 16th and the 26th day of the month during which the labor was performed, and labor performed between the 16th and the last day, inclusive, of any calendar month, must be paid for between the 1st and 10th day of the following month.

Based on the facts you provided, it sounds like even after providing the missing paperwork you were not paid on the regularly scheduled pay date. This would be a violation of California law. You should speak with an employment lawyer to determine your options.
