I don’t care why you got laid-off or fired from your last job. You shouldn’t care either. No one cares about your “feelings” as to why your previous company let you go. Once it’s done, it’s done. All you can do is move forward. The why or the how or the anger you harbor about your previous employer is really irrelevant to finding new employment. In fact, all of these things can actually stop you from finding a new job.
You need the company that laid you off to support you in finding a new job. You need them to be your ally and champion. With a reliable reference from a previous employer, getting your next gig becomes much more manageable. If you bad mouth your previous company publicly (regardless of if it is warranted or not), two things are going to happen. First, your former company will find out about your unkind words and refuse to provide a reference for you. Second, the prospective company you want to work for will find out and not want to take a chance that you’ll do the same to them. It’s a lose-lose situation.
Don’t burn bridges. You never know when you’ll need help getting across the river.
