Me and three other colleagues started in a brand new department recently. We keep making so many mistakes and my manager is really, really annoyed at us. They are pretty careless mistakes that have really severe implications. My manager had a conversation with us all saying that it's unacceptable and can't happen, I didn't like her tone as it sounded like our jobs were on the line.
I have played over things in my head and all of the serious mistakes I know were not me. There are other mistakes that are less serious and just things that can happen when you are learning a new procedure but I know I've not made any serious mistakes. Some of the mistakes I have made are down to poor training and lack of communication, for example in my old department we always did something a particular way which I then did in this new department only to hear it is different in this department (which it shouldn't be as it's a general site policy rather than a departmental policy).
Now because of my colleagues making serious mistakes I am terrified of doing anything wrong and I feel like I can't allow myself grace to be new and still in training, I need to be 100% perfect as there is no more room for error thanks to my colleagues.
There is no proof of who did what, we are a team and all responsible. I now feel like I need to babysit my colleagues and watch them in the corner of my eye.
I keep crying and am really tearful, can't sleep at night, etc because I'm so worried about it.
