you are no longer an employee and your contact with the nlrb was post employment so they are not retaliating against an employee
You were not terminated for contacting the nlrb. You keep trying to twist this into some improper action by the employer. The fact is they terminated you for whatever reason they did and you’re having a hissy fit because you got fired.
seriously dude, stop trying to get hired where you aren’t wanted. You are edging closer and closer to illegal activity.
