You must be a psychiatrist

@CallMeDave hahaha almost

I thought that but they tend to completely disregard other people rather than underminding their achievements. In addition they are likely to use other people to enhance their own amplified view of self worth.

@Amisja This is the closest personality disorder that fits the OP question. We know the lengths the biggest, orangest narcissist has gone to undermine other people.

@Green_eyes Yes on second thoughts, I worked with a nurse who would balantly lie about her own achievements and do absolutely anything she could to 'drop others in it'. We used to call her 'datix' Helen (datix being the name of the incident form we had to complete) She was a complete sycophant when it came to senior staff (choosing her break to coincide with theirs) and very slowly managed to slide up the slippery pole to management. She was definitely a narcissist and actually when she came under scrutiny she immediately fell apart. She is no longer a nurse and only just managed to avoid being struck off. You might be correct (do you work in MH btw? )

@Amisja no, not mental health. I’ve worked as an open heart RN for 25 years. My psych training is long ago.
