> the issue that was addressed with this ruling was people who'd clock out and then continue to work or where there is no clock and people simply write down how long they worked

No, this ruling cannot prevent this practice at all. How could it, without a government official standing watch?

You rely on employees or former employees raising an issue and investigating. There is little money to be saved by not paying bob for 15 minutes that one time. Companies that abuse this do so pervasively and consistently providing ample evidence of their misdeeds.

Alternatively employees can raise the matter in court where the additional incentive of money paid to settle the claim makes it worthy of a lawyer handling the matter purely based on expectation of obtaining a cut of the money.

It's not uncommon to have random samples taken by officials. They'll just show up, make a list of everyone clocked in and then interview a few (or all) workers. If they find someone who isn't clocked in, that is a big issue for the employer.

Plus, accurate records are a good basis for any lawsuit in case an employee claims they worked unpaid overtime.

How many European countries don't do random control?
