Hello,

I am an employer in Texas and would like to know the proper documentation required to terminate an employee (Voluntarily, Involuntarily, and Administrative).

Thanks!

Proper and legally required are two different things. However, here is a checklist prepared by the TWC that may help.

Do you have any specific questions?
