If the company is required to comply with Federal wage and hour laws, time and one half should be paid to non-exempt employees for all hours worked over 40 in the work week. Contact your nearest U.S. Department of Labor office for more information. The only mandatory break laws apply to children under the age of 16. If you are 16 or older, it is up to the employer. The employer may wait until the pay day designated for the pay period regardless of whether you quit or were fired.
Deductions can be legal, depending upon the circumstances.
If you are concerned that your employer may be taking illegal deductions, you should contact the state Wage and Hour Division for more information.
