A no call/no show might be an arrest situation–what now?

Q: “An employee did not show for work for three days of scheduled shifts. Normally, three no call/no shows are considered job abandonment and result in termination; however, we are suspicious that the employee may have been arrested. We have attempted to contact him on several occasions and have reached out to his emergency contact with no response back. Any recommendations on how to handle this situation?” – Katherine, Pennsylvania
