Answer:
The correct answer is letter "C": Individual.
Step-by-step explanation:
A grievance is a formal complaint raised by an employee against his or her employer. Grievances have three types: Individual, Group, and Policy or Union Grievance. Individual grievances are filed when employees feel their rights have been violated by collective agreements usually not of knowledge of the worker raising the claim. If for any reason in such cases the employee decides not to grieve, the union can do it on his or her behalf.
