A firm has around 30 employees and requires one year of service before an employee can participate in the plan. A new partner was brought into the firm who will become a HCE at some point in the next year. He has been allowed to join the plan without fulfilling the 1 year of service. Is this possible? Are they breaking any discrimination testing rules? Are there impacts to other HCE employees or NHCE employees? or Employees who have yet to get the 1 year of service rule. Thanks!
