I once employed a JW, was fine for a while until they wanted to live a double life. When it was found out I told them it didn't bother me as I am in no position to judge, and I didn't care what they did outside of office hours and that it would not affect their employment as far as i was concerned. Trouble was they were hounded by the elders, they had a breakdown and they stopped working costing me several thousands of pounds (no exaggeration!) to rectify the problems they caused by their breakdown due to the harrassment they were getting from the elders.
I was once employed when I was a teenager by a firm owned by JWs, also a disaster, never again will I ask a JW to do anything for me.
