We stopped hiring fellow JW's many years ago - our business is retail (not night time cleaning or handyman trades or service/labor). They felt entitled in many ways - could bend the 'rules' without repercussion or held special exception. Try firing an employee on Friday and going to the meeting on Sunday....talk about getting shunned!
We've also made it a rule not to hire JW's for any work around the home or on the vehicles. They'll jab you every time - right in the wallet and think it's okay to be late, sloppy, never on schedule or leave the job incomplete.
In the US, many young JW's are homeschooled - and are put to work in the 'family business' by age 12 or 13 during regular school hours (plus service time of course) ....
