My dad had a government job where the move was to enforce all contractual obligations rigorously, remove any benefits provided, and give them absolutely 0 work to do.
He had a disagreement with his manager (let's leave it at that, heh), and over the next week, his arrangement to work from a different office (the rest of his team were based in this office too, just his department's office was technically somewhere else) was removed, his flex was removed, he was taken off all projects, and told that using his computer for non-work purposes was a disciplinary offence.
He had a 90 minute each way commute, was required to be clocked in between 9:30 and 4:30 every day (not 9:31, 9:30), required to work 37.5 hours, requests for using TOIL due to commute or other issues were immediately denied, no work to do, and not being allowed to use the computer in his office. The resolution was he found someone in a different department in the city we lived in that had the exact same thing happen to them, and they negotiated a swap with each other and things got better again.

Point being, these processes are a combination of ass-covering, parallel construction, and outright abuse. Nobody deserves to be treated like he was (or like people are being treated in these PIP programs), it would be more humane for everyone if we did something different.
