YES! Every USW contract must include a legal grievance procedure and that means you have representation when it comes to receiving any kind of penalty. NO MORE ONE SIDED INVESTIGATIONS!
With a Union, employers must prove they have just cause to impose a penalty. In many cases disciplines and suspensions are overturned because of improper, one sided investigations by employers. The fact is, without a Union employees are essentially on probation for life. You have no recourse or back-Up.
