Get your job back? No. If they want to fire you, they can. If it is proved they did not fire you for a good or valid reason, you may be able to qualify for unemployment benefits, depending on how long you have worked there and for other covered employers in the last 2 years. File for unemployment right away. If there are people who say that you did not do what you were accused of doing, you may be able to have them state at the unemployment hearing (if you have one) what they saw, and you may get approved to draw benefits, no matter what your employers said. But there's no way, lying or telling the truth, fair or unfair, you can force them to give you the job back if they don't want to in an at-will state, and I bet you live in one.
