First up, IANAL.
The National Labor Relations Board recently ruled [McLaren Macomb, Case No. 07-CA-263041 (2/21/2023)] that Confidentiality and Non-Disparagement clauses in separation agreements are unlawful. The decision may be appealed and overturned, but this ruling may impact any who were recently or will be let go from CSG.
