Firstly,your son's supervisors and Center manager Don't care,at all ,not even a little and there is absolutely NO accountability when Management screws things up. If your son is having problems call the Union Hall and talk to the person in charge of Benefits as well as his Business Agent. . In the future if your son has ANY questions have him start with his steward,Then work his way up to his BA. He also needs to go to monthly Union Meetings where many subjects like this are covered and he will get the information he needs. NEVER ask management for anything
