Last July, I wrote about efforts by the National Labor Relations Board to argue that certain language in at-will provisions violated section 7 of the National Labor Relations Act. As of yesterday, the NLRB has clarified its position on at-will disclaimers. In doing so, the Board specifically approved a provision saying that the employee's at will status could only be changed in a writing signed by the company president.
This seems to me more like an "about face" than a "clarification." But either way, it's good news for employers.
