to not want to pass on my skills for free?

[newsparklythings]

The background here is before I had children I worked at a higher level and a different field. I have one child so far. Have taken on a lower level position which I enjoy but is not as challenging. It has good flexible working options.

Quite a few staff including some recent recruits are on a contract earning more than me (we are on bandings, they may earn £10k more per year for example). They are mostly younger, and male though not all.

I have been asked a few times if I could 'just' pass on some of my training / abilities to these staff, as managers (not necessarily those who recruited them, they were given them to manage) identify there is a gap between the employees' competency and what their jobs involve.

AIBU to feel a bit put out about this? I haven't got a problem with the concept of supporting colleagues. My job description doesn't exactly match what I do anyway and I acknowledge it is part of being at work that we share skills. This is more along the lines of 'could you just train them in Prince2'

I suppose my reluctance stems from feeling my skills are what give me my value in the workplace, and I have had to pay for a number of qualifications from my own pocket.

It’s remuneration - may as well spell it correctly if you’re going to ask for more money...

Do they know all about your training? Rather than just your skills. It’s a good opportunity to say to them “to get my skills I had to invest in two weeks full-time training and exams etc. It cost me £x,000 in fees”.
At that point you need to work out what you want. Promotion yourself?? There’s no reason you can’t be appreciated for your actual skill and still have some flexibility. It’s just not true that parents who want to fulfill their parenting commitments necessarily have to work far below their capabilities.
