Unfortunately, words on paper frequently fail to prevent organizations, public of private, from doing things they are technically not allowed to do. See the security state apparatus of any of the nations around the world including the 5, 9 and 14 eyes, or any number of tech companies that claim and market privacy respective policies only for people to uncover later that what they pitch publicly diverges in spirit from what they do or what is in the actual terms of service.
Hopefully if people find their employer going outside the bounds of the contract they can catch it, catalog it and hold them to account. Accountability can often be tricky and costly though.

This is why unions and NGOs exist.
