Concerns regarding appointee performance may include extended absences without adequate explanation, repeated non-compliance with university lab safety procedures, inability to perform basic research techniques expected of someone with similar training, and other related issues affecting scholarly competence. 

Steps for Faculty Mentors:

1. Informal Resolution: The faculty mentor should first attempt to resolve these issues informally through discussion with the appointee. It is important to document these attempts.

2. Probationary Period: If no progress is made, the mentor should draft a letter to the appointee, placing them on a one-month probationary period. This letter must include: 

   1. The expectations that must be met to continue the appointment. 

   2. A statement that failure to meet these expectations will result in termination at the end of the one-month period.

3. Documentation: A copy of this letter should be sent to Postdoctoral Affairs for their records.

4. Notification of OISS: If the departing appointee holds non-immigrant status (e.g., J-1, H-1B, TN) and resigns before the end of the appointment, the department must notify the Office of International Students and Scholars (OISS). For further information, visit OISS Leaving Yale.

By following these steps, faculty mentors can address performance issues effectively while ensuring compliance with university policies.
