Upon taking over a contract from my original employer (ABM Insustries), a great deal of my former coworkers were told that they did not pass a background check that we previously passed for ABM as well as for customs. Upon trying to speak with someone to get a better understanding of how that outcome was possible considering the fact that myself and a great deal of my other colleagues were already employed, I myself was unable to speak with anyone other than the receptionist and that was after going to the office because no phone numbers were provided.
