Plans, Perks & Pay | Employee Benefits & Executive Compensation Blog

There are both single-employer pension plans and multiple employer plans (MEPs). In a single-employer plan, only employees within the same “controlled group” of businesses are allowed to participate.

And all of those employers’ employees are able to participate in one plan.
