Typically, a plan includes a mix of rank-and-file employees and owners/managers. However, some employees may be excluded from a plan if they:
- Have not attained a specified age;
- Have not completed hours of service;
- Belong to an excluded class of employees; or
- Are covered by a collective bargaining agreement that does not provide for participation in the plan, if retirement benefits were the subject of good faith bargaining.
Employees cannot be excluded from a plan merely because they are older workers.
