I'm looking at a plan that covers bargaining unit and non-BU employees. The plan provides a general benefit of 1.5% x years of service x final average salary for all employees, but BU employees make mandatory contributions and get a 2% multiplier and an early retirement benefit. The plan was amended a few years back to provide that BU members who move into a non-BU position retain their eligibility for the better benefits, but they must continue to make the mandatory contributions. Thus, with respect to non-BU participants in the plan, some, but not all, individuals must make mandatory contributions (and receive the better benefits). This is not a voluntary arrangement -- all former BU employees must make the contributions, and the other non-BU employees may not contribute to receive better benefits. None of the employees are highly compensated.
Does anyone know of any reason this arrangement is not permissible? In particular, whether the employer can require contributions from a subset of employees.
Thanks!
