So I was recently terminated (fired, officially on paper as laid off) from employment. Friday I was talking about the need to hire someone to manage a system we had no one officially to manage. I was already working 2 roles, and they wanted me to do that. I was temporarily tasked with implementing a new system for tracking services and field technician dispatches, which was then supposed to be handed off to the dispatching department (and it was). Anytime I asked about being able to train someone on how to manage the system, there was all kinds of negative response. And this was going to be the backbone of the entire dispatching department.
Everyone just kept complaining it would be too expensive, and I tried to pose the example of "What happens if I'm not in a position to work here any more? I implemented this system, and if I'm not able to train anyone on how to use it, you will have absolutely nobody to support it."
The following Monday, my manager comes to me and told me the company owner said it was my last day because he 'heard a rumor I was looking for a new job'. There was no questions asked, no severance, none of my vacation time got paid out(the company never pays out vacation time, which I think is legal). Literally just 'today is your last day'. And now they genuinely do have nobody to support it.
Is there anything I can do about the situation despite putting in as many job applications as I can? (which I am now doing)
