Per sound advice from a PO yrs. ago, I avoid any/all employment situations where witnesses are involved. Couple yrs. ago had couple JW thugs working (construction) via my licensed contractor's crew. Told contractor they were done -- not allowed on my property and security would not be allowing any future entrance. He found out for himself the losers' work ethics and within a day terminated them from company. He'd blindly trusted them because of another JW employee's theatrics - I laughed when he told me and filled him in.
It's the same regardless the religion -- church goers love trashing house while cleaning, etc., etc. Have cameras but big deal.
