Final answer:
A grievant who receives notice of potential dismissal for repeated misconduct may be discharged if the incident repeats, but the dismissal can still be subject to arbitration which considers the specific circumstances.
Step-by-step explanation:
The question pertains to the rights and procedures following a notice of potential dismissal due to misconduct in the workplace.
The correct answer is that a grievant who receives notice that a similar incident of misconduct will be "subject to dismissal" may be discharged if he/she repeats that incident, based on a consideration of the specific circumstances surrounding the infraction.
Advance notice does not automatically preclude the discharge from being reviewed by an arbitrator. Arbitration, a standard part of many labor agreements, serves to ensure fair treatment and due process, considering all specifics before a final decision on dismissal is made.
