A statistical examination of the effects of reinstatement on the employee’s behavior and the behavior of other employees, and its effects on the management-union relationship. Seniority and the terms of reinstatement are found to affect whether an employee returns to work. There is little evidence that reinstatement results in a deterioration of the performance of other employees. Awards of reinstatement without back pay that serve as an “easy way out” for the arbitrator are discouraged.
