whats up with these people please read?

Ok its a bit long but bare with me. My son who is 17 has been working for a small roofing comp. He enjoys working and works hard. to prove that, he gets a 50cent raise like every other paycheck. he started at 7 hr and now is up to 9.00. Just last week thurs.he was fired. He calls me really upset to pick him up since he has no car (hes saving for one)I asked him what happened he said he was working and all of a sudden out of the blue hes told hes fired cause he wasnt wasnt working hard enough. And what was weird was that the guy who fired him (John)was just another worker who'd only been working for 10 months and not his boss Larry. But Larry was there when John fired him but he didnt say anything. So there i go to pick him up in the next town cause John said that Larry wasnt going to take him home. Anyway my son was really bummed out. as soon as we got home he called around for other jobs. I told my son to call Larry and ask why he let John fire him and that if he wasnt working hard enough then why all the pay raises. My son says that he is mistreated and he feels its cause he is not a Jehovas Witness. everyone who works in this little comp. is a JW. and Larry has envited my son to attend Jw meetings. and I feel that he is trying to convert my son into becomeing a JW. my son was raised Catholic. My son had gone a few times cause he feels pressured and wants to be on Larrys good side.Well my son told larry that his GF is preg. and will have to find a second job. Since then they have treated him badly saying he shouldnt be fornicating cause that was a sin. Well. just this past Sun. my son got the nerve to call larry and ask why he allowed john to fire him larry told him that they were just joking. that he could have his job back. My son asked why he didnt call and tell him so larry tells him he was waiting for my son to call. this is a really cruel joke my son was bummed out all weekend and worried he wasnt going to get another job fast enough. i told my son he should complain but he doesnt want to hes just happy he got his job back. he feels john just doesnt like him and since john is a close family friend to larry i guess he felt he had the authority to fire. I feel that this is just so wrong. and that larry should of said something to john the moment he told my son he was fired. instead of making me drive 15 miles to the next town and try to find where my son was working at to pick him up. My son says he is left out eating lunch in the work truck while the others dine at a restraunt. My son says john has thrown crow bars at him instead of away from him while he is picking up shingles from the ground and is told that he was just trying to scare him. His boss larry thinks all of this is funny. I dont see anything funny about it and it makes me soo mad. But my son doesnt want to make matters worse. He just wants to work. Ive thought about calling the comp owner who is Larrys father since he was the one who hired my son in the first place but i feel that my son is old enough to handle these things on his own he will be 18 in a few months and will be legally an adult. MOMMY cant be handling his affairs anymore. and i dont want to make things worse for him at work. Knowing John hed prob. make fun of my son for having his mother but in. Does anyone else agree with me and do you think it all boils down to religion? Please let me know what you think.
