Maybe not the training manager, but a hub or center manager can remove her from her safety co-chair position.
Disagreed. Article 18 is explicit in stating that the local union shall appoint the union participants on the safety committees. The union members then select the co chair; management has absolutely no right to tell us who sits on the committee or co chairs.
"Corporate statement" sounds pretty vague but Article 18 also states that no bargaining unit members shall be identified in any safety paperwork done by the committee or co chair. Is this related to an accident or a professional conduct issue?
Usually the problem with the commitee/CHSP co chair are them being filled with rats not people unwilling to write a statement for the company.
Agreed with Mug on the statement. The company can never compel a statement from an hourly but neither can an hourly seek to impede an investigation. Keep in mind that no one has ever been fired for simply saying, "I don't remember."
