You're working in an organization with a union and a contract which provides a progressive disciple policy. Your coworker never does his job properly and has a very poor attitude. The manager never does anythinf about it until one day she's fed up and fired him. Even though the union is aware of this employee that he's bad at his job, they file a grievance against his termination and the employees request. Why would the union file this grievance for the employee? What is the likely outcome from this grievance?
