Temp hires are kids in school and trainees etc that would almost always have a 3 month contract that then get full time work when they know it will work out. Some elder care companies I know kept hiring new workers constantly and it did not go over well for any of them. Shut down by unions and most old people switched away from these, also the communal overseers removed them from the hiring pools and from recommendations as a choice of provider. All workplaces I have quit, have treated me well, mostly using the time to transfer skills and documentation to a replacement and then saying I don’t have to come in when it seems done. Two times they gave me instant “garden leave” with full benefits which means I get full pay but don’t have to work and if I have other work I can get double salary without having to pay penalties. I also am in a union that by law has to be asked automatically to come in and manage the transfer, those are people that have seen hundreds of layoffs and leavings that can give each party a sense of what is expected, and raise issues or irregular things like you describe to the correct authority. I have not seen any abuse of this law (law of labor safety) from a company or heard of any abuse of the law in my entire forty years of life. It’s because it is taught in schools and taken very seriously by even small businesses.
