If Texas is an at will work state they dont need any reason
Usually people are let go because they dont fit in, theyre not producing enough, the company is down sizing. Less often people are let go for theft, harassment, disobeying the boss
I know from personal experience, companies will appeal it to the bitter end. They dont want to see their rate go up, so they drag it out, hoping you give up.
Keep your cool, stick to the facts.
Probably more this than anything else. Am not a heavy smoker, don't use curse words for adjectives and go to work early and leave late. Yeah, didn't fit in, I guess. lol. Going to try for that one check as a matter of principle anyway.
