Closure of business as a basis for employee termination

Dear PAO,

My cousin worked for a private company that manufactures and supplies school materials. Unfortunately, their office and warehouse were gutted by fire. As a result, he and his co-workers were left without work because all the company equipment and materials were destroyed. For several months, my cousin had to take odd jobs to support his family while waiting for the company to resume operations. Recently, they learned that the company had resumed its operations, but they never received any call or notice from their employer despite constantly messaging their supervisor to ask for updates.
