The last factory I worked at moved a temp service right into some front office space.
Temps aren’t really cheap but there is the advantage of them being easy to get rid of, the hassle of paperwork, and insurance issues.
A lot of businesses seem to like hiring temps. They don’t have to pay insurance benefits or any other benefits that way. And like you said, it’s easy to get rid of some of the employees.
On the flip side, there are people who only work through temp agencies. They don’t want careers; they get bored working at one place for very long. So they’re temps and work one place for a few weeks, then get sent to another job for a few months.
I don’t know what the temp situation is at Tyson. I imagine with it being nasty work, they use a lot of temps because the turnover rate is high.
