Sorry it's a bit long.
I work with a man who is a more senior member on our team at work than me. We work in projects that last at least 6months at a time.
He (the Senior) was given 2 projects last year which needed to be worked on continuously with a big report written at the end.
Our Boss asks for updates at team meeting going round saying how you are getting on etc.
The Senior has been saying at these meetings everything is going great. However just when these projects need completed he goes off on sick. So our boss asked me to pick up the projects eg tart up the report that should have been written. Only problem was I couldn't find them. The files were empty. Problem was that as Senior was off sick, boss can't ask him about ongoing work encase it stresses Senior out.
Long story short I had to work extra to essentially do the work of 2 6 mnths projects in 6days. Not fun. Boss was impressed I managed.
Senior came back today and discovered I had completed his projects and the Boss has given me credit for them. I'll be presenting them to management. This is a big deal for someone of my level.
Senior has had a go at me saying I have shafted him. I had stolen his projects etc. I told him to speak to the boss about it. It was his decision. So I told my boss after that, that senior had a go and suggested they talk. Boss later was in his room with senior I can only guess talking about the projects.
After that senior came over and offered to come to the project presentations with me to 'help out' I just mmmm him and said I'll let him know if I need help.
Aibu to say no to him coming with? I didn't use any of his work and did it all myself and I'm worried he will try to make out that he somehow was involved in front of management. He has form for sneakily trying to take credit, big himself up in front of management. Management who are essentially all all boys club type of thing.
