My question involves labor and employment law for the state of: NJ

I am writing with a question about the conduct of a district sales manager during quarterly job performance evaluations.

In a sales office, the employee is consistently the top performer in terms of sales and commission for both the office and personally. The employee is always dressed neatly and professionally.

However, during the last two performance evaluations, the district manager (who is not based out of the same office) began the conversations by commenting that the employee was "too thin", "looked sick" and "wasn't happy". The district manager is not a physician, qualified to make such "diagnosis'", nor was she asked for her opinions.

Is it legal for a manager to make such comments to an employee? Particularly in the realm of a performance evaluation, the behavior seems questionable at best?

Is there recourse for the employee in such a scenario?
