Eligibility for an employee related to shareholder.

[Guest Sppedraza]

Would the following employee be eligible to join a cafeteria plan, assuming they meet basic eligibility? It is the same person employed by two different companies.

The employee is a plan trustee, former company officer - 3 years ago, and sibling to 80% shareholder of S-Corp.

The same employee is employed with this other separate company,is the spouse to the General Manager/Trustee, is a company officer/Trustee, and is the "child(of adult age)" of the 100% shareholder of the second S-Corp?

Thank you for any assistance.
