release me

Hello Forumites:

I would like your input for a possibly hypothetical situation.

Situation: Employee takes FMLA leave for illness that may affect their mental capabilities. Employee, who works with clients, wants to come back to work part time. Employer asks for doctor's release. How can employer protect client relationships if the employee is not quite up to par mentally?

If I am correct, employer cannot go back to doctor after the employee gets the release. Does the employer have to just trust the release? Is there a way to word the request for release that might help? Is there any way to make sure the employee is up to par before letting them talk to clients? Any suggestions? :help:
