Hi Pattie

Sorry to hear your son is getting pushed around by these jerks. I was in the same boat in 1999 but here in Canada if you were on the Job for atleast 1 year and had a note from the Doctor they could NOT get rid of you and if the Note says NOT to do any lifting or bending then he should NOT do any. Alot of places try to push their people around because the workers are to afraid to lose their jobs and just do what they are told.
Your son should ask his Boss just how old you must be to have a Back Problem and then ask for it in writing from him as well. That way you have something to fight back with if they do get rid of him. Check your Labour Laws where you live to see just what can be done about this before he is let go and tell them just what his Boss says about being to yound to have a Back Problem.
