So my manager told me to stop discussing wages with my coworkers

Among other things but what the fuck do I do now? The nearest NLRB is in another state. I don’t want to quit but I can’t fucking do this toxic shit anymore. I think I’ll file an online charge against them but holy hell I just want to leave. I don’t want to go in tomorrow. I’m fucking tired of this I’m fuckinf tired of work related trauma
