I was fired on my first day at work today. This is the first time. This experience is too bad for me. I am a proud person. Besides, I didn't make any big mistakes today. Strictly speaking, the small mistake may be because I got off work on time and didn't go to the office to tell the supervisor who was in a meeting that I was at home. Besides, I talked to her without calling the supervisor. Other colleagues are working overtime. I'm a newcomer.
