Nope. There's all sorts of contractual oblications to the staffing company as well. Europe doesn't have at-will employement so the staffing company that signs a contract to supply a fixed worker for 18 months does have a say on the matter. If there was something like a "buy an hour of labor, with the vendor company handling all supervisory stuff" then it would be easy. This was not the case.
Nonsense. The entire legal framework of temp agency work is built on the fact that the agency is the employer, not your company. If a contractor is a safety risk or incompetent, you send them back to the agency. If you "parked" a dangerous person at a bench for a year and a half just to avoid an HR ticket, that was a choice made by your own leadership, not "US brainrot."
How much experience you have with training and running a team? You will get a lot of people that are really really thick and training them is like trying to teach algebra to a cat.
Which makes your company's decision to rehire and retrain every 18 months just to avoid paying benefits to employees look a lot worse.
Why not? Do you have something against nurses and think that they are stupid? There were a few base degrees that worked well for our purposes and nurses was one of those, not many applied tho since most of them were busy at nursing jobs probably. Other good degrees were chemistry related and somewhat surprisingly mechanical degrees. PhDs were always a pretty solid bet though. Naturally we couldn't pick the best ones since we had the gender/race quotas to abide to so.
Legislation here dictates that contractors are in all purposes the same as regular FTEs and yes DEI is a massive brainrot. You check out your identity when you stamp in. At work your identity is "corporate drone", corporate drones are genderless, raceless and a-political. Once you clock out, you can be whatever you feel like.
You seem to be all over the place here. Are the nurses the "really good" workers you only found because DEI forced you to look outside your preferred pool, or were they always a "base degree"? Are PhDs people who take too many two hour toilet breaks, or are they a "solid bet"? You keep saying you can't pick "the best ones" because of DEI, yet you admit the nurses you hire solely because of your company's DEI policy are excellent,
and that the tools themselves keep the output consistent regardless of the person. You're even flip-flopping on the job itself, claiming it's a role "anyone with a pulse who speaks English" can do, while simultaneously complaining that training people is as impossible as "teaching algebra to a cat."
Finally, you say workers should be "genderless, raceless corporate drones," yet you're the one who says you were guessing backgrounds based on names to hit a recruitment quota. You weren't even treating them as drones. You were treating them as lottery tickets to get yourself paid, and it sounds like you were actively gaming the system and ignoring safety risks just to secure your own bonus.
