The employer may have been asking those nosey questions about why the OP couldn't come back two days earlier, when she was scheduled to return in an effort to determine if it was due to health or medical reasons. If you had been unable to return and were fired because of it, and you could provide medical evidence that you were unable to come back due to a medical reason, with proof of such it would not prohibit the company from firing you for not coming back if they wanted to, but the system would very likely approve your unemployment benefits under this sort of case. The unemployment system would say that you could not help getting sick, or having a family member get sick. Any other excuses, such as a broken down car, having too much fun with the family, had another social event I wanted to attend.... those are all personal reasons, and they can fire you handily for those. Unemployment benefits are generally not approved under those circumstances. Did you call in and tell them you were going to be out the two or three additional days? That's a very important question, as no call /no show is almost always considered good grounds for termination.
I fail to see what tranquility says, that you're going to need an attorney. To fight this with who? You can appeal the initial decision denying benefits, but if you were in any way aware that this two day extra absence might result in your losing your job, and you can't provide an excellent reason why you were forced to take it, I don't see as you have a legal leg to stand on. legally terminated, and probably no unemployment benefits is what I am seeing here. Your union rep gave you execllent advice. When you are suspended with no pay, you file for unemployment right away, whether you are going to continue to fight it out with the company or not. Frankly don't see a lengthy fight as a possibility here anyway. You did it. You chose not to say why or to ask your employer to have compassion with you for any good reason you could have given them, told them basically to bug off, it was your personal business, and they said, "Okay, you're fired." They could do this.
REturn the letter stating that you wish to appeal the unemployment decision. You do not need to present your argument at this time, you'll either have a telephone or in person hearing at which you'll be appealing your decision. Indicentally, I do not have a job or any other source of income is not part of the appeal. This appeal will be strictly based on whether or not you had a valid non-misconduct reason that you were out those last two extra days, and do expect that you will be asked the reason you were out.
