Is the 7-minute rule legal?

Yes — rounding time punches to the nearest quarter hour is permitted under US federal law as long as it is applied neutrally and consistently (neither systematically favoring the employer nor the employee), and employees are paid for all time worked.

Does rounding ever favor the employee?

Yes — the rule is symmetric: shifts ending 8–14 minutes past a quarter hour round UP in the employee's favor, just as 1–7 minutes round down.
