# The Green Shield: How Pro-Environmental Advocacy Protects Employees from Supervisor Ostracism

## TL;DR

Employees can reduce supervisor ostracism by advocating for environmental causes, which signals moral character and earns social credit.

## Contribution

The study introduces green advocacy as a proactive behavior that protects employees from supervisor ostracism through signaling moral character.

## Key findings

- Green advocacy leads supervisors to grant interpersonal moral credits, reducing their intent to ostracize employees.
- Employees who engage in green advocacy report lower perceived ostracism in real workplace settings.
- The protective effect of green advocacy is stronger when supervisors support environmental initiatives.

## Abstract

Supervisor ostracism represents a pervasive and detrimental workplace stressor, yet existing research has predominantly focused on reactive coping mechanisms, leaving a critical gap regarding how employees can proactively prevent such mistreatment. To address this problem, this study draws on signaling theory as an overarching framework—integrated with social exchange theory as a downstream mechanism—to propose that employees can actively construct a “moral shield” by engaging in green advocacy, a high-cost, self-transcendent behavior that signals intrinsic moral character. We tested our theoretical model using a multi-method design. Study 1, a scenario-based experiment with 146 supervisors, provided causal evidence that green advocacy leads supervisors to objectively grant interpersonal moral credits, which subsequently reduces their behavioral intentions to ostracize. Study 2, a three-wave time-lagged survey of 434 employees, complemented these findings by confirming that green advocacy is associated with employees’ perceived moral credits and reduced perceived ostracism in a field setting. Furthermore, we found that this signaling process is contingent upon the receiver’s interpretation: the protective effect of green advocacy is amplified when Supervisory Support for the Environment (SSE) is high. This research contributes to the literature by identifying a novel, behavior-based signaling strategy for averting social exclusion and validating the dual nature (granted vs. perceived) of moral credits in hierarchical interactions.
