Not going into too much detail as can be outing..
History... public service job.... permanent staff with overall 8 years service.
Started new job within company in June. Loved it to start with despite very difficult and trivial dept. Job is very specific to one single topic which I won't disclose.
New member of staff started 3m after me and has basically made my life hell to the point I'm questioning my ability. Feedback before they started was "I have hit the ground running" etc but since they started and got involved, it's "I am questioning your capability".
The member of staff is a bullshitter - has everyone wrapped around their finger and everyone idolises them. I have seen through the act and can't stand them. I have been standing up for myself but now I can't as I'm too scared to as I get hit with big formal emails where our boss sides with this other staff member. This other staff member works with me with this singular piece of work but I have already raised concerns about their attitude to me to the big boss but that achieved absolutely nothing!
I'm now at the stage there is a job been advertised on the internal system and I'm tempted to apply for it. It's with a dept that I am very familiar with but it is a pay scale down from me. The way the scales work is id be the same salary as now but that's it, no progression from there salary wise, but with this job now I can increase by £6k within 5 years....
I am miserable at work. People side with this other staff member and see me as the one digging my heels in. The job itself isn't really fully as advertised either, so I'm doing more generic office duties rather than this one specific project. I don't know what to do..! Stay where I am and suck it up or get the hell out of there in a lower paid job in the long term but be happy!
