It sets the rules, workers will have to fight for it to be followed still. But sociopathic management now knows workers have a foot to stand on in court, enterprises will be inclined to make it policy. Less sociopathic management might realise they were being assholes and dial it back a bit. Some managers genuinely don't realise that the current "norm" is not fair, since they are deep in the zeitgeist.

Countless exceptions sure but there's no denying this is a good attempt at change.
