Final answer:
The relationship between the union steward and first-line supervisor is best described as a power relationship due to the conflicting interests and influence over the grievant. While collaboration is important, the roles inherently lead to a struggle for influence within the organizational structure.
Step-by-step explanation:
The relationship between the union steward and the first-line supervisor in the context of competing for the grievant's attention is best described as a power relationship. This term applies because both the union steward and the supervisor may have conflicting interests and are likely in a position where they exert influence or control over the grievant, each with their own set of goals and agendas.
In the mentioned scenario, it is important to understand that power dynamics are often at play in the workplace, especially in situations involving grievances. The union steward represents the interests of the employees and seeks to protect their rights within the organizational framework while the supervisor represents management's interests and may prioritize the organization's broader goals which can be at odds with individual employee's concerns.
Overall, while efforts towards collaboration and mutual respect are essential, the inherent roles that a union steward and first-line supervisor play often result in a power struggle, as each party seeks to assert their influence over the situation.
