If a state law requires employers to give employees one day off per week, an employee who works that one day may be entitled to overtime pay under federal law.

Under the Fair Labor Standards Act (FLSA), federal law does not require overtime pay for working on weekends or holidays unless it results in the employee working more than 40 hours in a workweek. However, if a state law mandates a day off and an employee works on that day, leading to more than 40 hours worked in the week, the employee could be entitled to overtime pay under federal law for hours worked over 40 in a workweek.
