It's law, but it still gets abused quite frequently (outside of tech, at least). Anecdotally speaking, all my mates who work in private construction office jobs regularly do quite a bit of unpaid overtime. It's very much a combined cultural and managerial issue, clocking off at the correct hours gets you the stink-eye, and the volume of work assigned necessitates overtime.
