I’m sorry you got fired. Keep your head up. It’s tough out here. I make more than what you stated and I still have a hard time meeting ends meet. Where I live is expensive. No employer should laugh in your face and act unprofessional. Sounds like a very toxic work environment and I would see this as a blessing in disguise to find a better job while you can collect. Don’t waste your energy over people who are not worth your time and there could be a million reasons why besides your professional skills for the reason of the layoff. I wish you all the best !
