” reasonable”
That is what the R stands for in NLRB.
I have too many friends who have worked at places like Intel and who lost their jobs only to have some contract firm like Siemens or CompuCom offer to hire them to do that same job at less pay and then arguing they’re exempt from California overtime because Siemens runs out of Washington State. Intel would not bother with this artifice if they could not get away with it.
