Nobody wants to hire "permanent" employees now for any reason, especially companies not located in right-to-work states. They try, like the company in the article, to get by with low-priced, younger workers for the short term, then complain about the inadequacy of those workers.
The answer (other than changing Presidents) is to change the laws to favorably treat the hiring of independent contractors. But the unions go ballistic every time that subject comes up.
"independent contractors" = no benefits and even less job security. Might be good for the employer, but awful for the employee.
