The moment leadership makes mistakes or decides you are not cult worthy, they put you on official or unofficial pips and give you no support or chance for success. HR only cares about the company and not the employees.
Though this did not impact me personally, I did have to go through this with 2 colleagues over the years and sworn to silence. I had to sit back and watch Diligent abuse and mistreat people because had I said anything to HR. I would have been next.
If you need a filler job to get you to the next one, Pick Diligent, just don't get comfortable and don't unpack. Just do your 8, get your money and look for another job. No pay and perks are worth the end result.
Scary to think of how many people this happens to because in the end, they make you sign away your rights to get a small little check.
