Today I got to work, opened my email, wandered off to make a cup of tea. Came back, initially just saw lots of unread messages. Put my specs on and realized I was in my colleagues email (we share the same computer and he had not logged out). And there I see it plain as day - he has forwarded an email that was sent to us both from the management team to another member of staff in a different department.
There was nothing untoward or confidential in it - it was just listing some instructions and updates. It was forwarded with a 'Oh god look what they are asking us to do now/here we go again' type title'.
I am fuming as I work closely with him and trusted him - we need to be able to work together as a team and some things need to be in confidence. He had no business to forward such an email on, it wasn't for other departments eyes. For context - There has recently been minor underlying grumps in the team on return to work in the office after lockdown and this kind of gossipy type sharing of information doesn't help. I am trying to smooth over cracks of where people are unhappy and he has breached my trust.
Not sure why I am posting! Just frustrated I can't tell anyone because I was (unintentionally) in his inbox. But glad I know where his loyalties stand as I had no idea. Feel like I want to tell him but can't!
