Random piss test for drugs definition: Employers ace in the hole to screw an employee out of workmans compensation. Come up dirty...HAD TO BE HIGH...case dismissed and your fired! No unemployment..do not pass go, do not collect $200!
This can also be used for termination for consistant absentee's or for being late on a somewhat consistant basis. Hell, maybe bossman didn't get laid the night before and picked you for a hostile outlet!
Unless my one of my job duties is fucking, bossman can leave my dick out of the equation. JUST SAY NO TO PISS TESTS!
