DP works in high pressure environment and has consistently received above average grades in performance reviews for the last few years.
However this year the feedback from their team has been less than favourable which had led to a reduced grade and bonus.
I don't know any of their team personally, but over the last few months my DP has been telling me about a troublemaker in the team that has been causing issues within the team. I suspect that this person may have been turning the team against my DP, although I have no evidence of this. However the fact is that many of them have provided negative feedback to DP's boss.
I have told DP they are playing up, but DP has a history of downplaying things and naively seeing only good in people.
DP wants to buy a gift for the team e.g. Box of chocs. I think that DP should not buy them anything, as they are being disloyal. Even if DP has failed somehow (and I doubt it as v. Hardworking and conciencious) they don't deserve a gift.
AIBU?
