RE: Help desk worker blindsided by a performance-related firing
You were not fired, they wanted to get rid of you for some reason and most likely to save money. They brought someone in who's probably a contractor. If you were so bad, why keep you on. As far as what to say to future employers, tell them you were downsized. First in first out. There's nothing you could have done to keep your job. Your direct manager was responsible for training you and making sure you were aware of the responsibilities of the job.
