Can We Consider This a Voluntary Resignation?

Question: An employee called out a few days ago by leaving a message with some vague information about being ill and hasn't followed up since. Can we consider this a voluntary resignation and start the termination process?
Answer from Janelle, SHRM-CP, SHRM-PMQ: Most likely not. There are many reasons why your employee might not have been in contact since leaving the original message, and since they mentioned illness, there's a good chance their absence is protected by law. Potential protections come from the federal Family and Medical Leave Act (FMLA) and Americans with Disabilities Act (ADA), state-level family and medical leaves and disability protections, state or local sick leave laws, and state-paid leave programs that come with job protections.
