Final answer:
Arbitrators tend to give union stewards more leeway in grievance meetings due to their role in representing members, but these stewards are not immune to all disciplinary actions. The National Labor Relations Act does offer protections for union activities but does not make union stewards immune to discharge
Step-by-step explanation:
The correct statement about employees who are union stewards is: b. Arbitrators give them more leeway than they would other employees for arguments/remarks made to management in a grievance meeting. Union stewards are often given a degree of protection when engaging in their duties, which includes representing union members in grievance meetings. This does not mean they are above the law or exempt from disciplinary actions, but their role necessitates a broader scope for argumentation and representation.
The National Labor Relations Act does offer protections for union activities but does not make union stewards immune to discharge; rather, it aims to prevent unfair labor practices. Furthermore, the idea of union stewards having less responsibility or being considered no differently than any other employee does not fully capture the special duties and protections associated with their role.
