Found this gem on Youtube. Microsoft hired temporary workers known as " Permatemps" from the early 90s to mid-90s. A group of contractors sued Microsoft and won successfully in court. The court (9th circuit) held that Microsoft was treating temporary workers in the same fashion as full-time employees and was side skirting IRS codes.
Cliff notes:
The contractor alleges he was not notified by his manager that internal positions were opening up and he was passed up for an FTE position. ( I've personally had this happen)
They dangled the carrot of "FTE positions" to contractors to trap them in a never-ending cycle of contractor work. ( sound familiar?)
Microsoft would have to pay the agency a " contingency fee" to convert them over to FTE. So they opt for the never-ending "Permatemp" stance.
Nike is literally mirroring the same tactics Microsoft did almost 30 years ago.
