Grievance Against a Co-worker

Since the agreement is between management and the union and not between individual employees, it is not applicable in the latter instances.

So, when is it applicable? When an employee violates the contract, like working overtime without getting paid, the grievance is against the employer. Or, if an employee sexually harasses a co-worker, the complaint is against the employer for not protecting the employee from sexual harassment.

Filing a grievance is not appropriate if an employee is taking too much time off or slacking at work since this is not a violation of the contract. An employee may not file a grievance against his/her supervisor if they think they are unprofessional or incompetent. Only if they manage poorly by violating a contractual provision, can you file a contract violation grievance.
