I work for a security company which is hired as an independent contractor by the warehouse management (WM). Guards are instructed by the WM to check the bags of the workers (all coming from temp agency) once they are leaving. I don't want to be accused of invading privacy, touching their bags, their stuff in the bags . . . ( and what not)! WM has found a good count of empty boxes with the stuff missing that is why they have asked us to beef up the security.
Also, can I write and paste this on the warehouse exit, both in English and Spanish (90% workers don't speak English), "Be Prepared to take your belongings out of your bags. No exceptions. Thank You."
