Which type of grievance involves actions taken regarding fines?

The choice of a Non-Injury Grievance is accurate because it encompasses disputes related to league or team-imposed fines that do not stem from player injuries. Non-Injury Grievances focus on issues related to conduct, financial penalties, and other disciplinary actions that may arise within the context of team or league policies. This type of grievance reflects the NFL's collective bargaining agreement provisions that allow agents and players to contest fines that the league or teams impose for various non-injury-related reasons.

In contrast, an Injury Grievance specifically pertains to disputes regarding a player’s injury status, eligibility for benefits due to injury, or related compensation claims. A Contract Grievance usually involves disputes about the interpretation of contractual terms or conditions between the player and the team, while a Team Policy Grievance generally relates to disputes about specific team rules or policies. Therefore, the context of fines aligns more appropriately with Non-Injury Grievances, confirming why this option is correct.
