One work colleague (Not line managed by me but will soon be) is quite annoying.
Always off with something going on, complains about how busy they always are when they have the least responsibility and output in our whole department, talks about how they turned down better paid jobs to stay like we should be grateful, talks about staff from other departments when she barely knows them, tries to talk people out of promotion opportunities by telling them how she is qualified for and has done that level of job before and wouldn't go for it (Even though they are on a development plan in their current job for absences and underperforming) and the most annoying thing is they share a desk with their partner ehen working from home so while on work calls they stop mid sentence and involve their partner.
They are also generally quite strange. A colleague invited them round for a drink with another colleague and she showed up with her husband, who the other had never met or invited and sat there all night. It was all apparently very awkward.
Think this may cause some headaches for me in the future. Not quite my enemy yet, but potential is there for the future.
