I have worked in the same job for many many years. The job has evolved over time as my children have become older and I have been able to learn more, train more and take on more responsibility. For the last 8 years or so I have been running all of my own caseload with limited imput. I am a fast worker (not a stealth boast) and I do all my own admin and type all of my own letters, contracts etc. My boss relies on me a lot and for the last several years he has been able to take two two week holidays a year and several other breaks. I know that if I wasn't here he wouldn't be able to do that. I received a big jump in pay say five years ago after a lot of negotiation. However, I don't think I earn enough for what I do. For perspective I live locally, no travel costs and get 6 weeks holiday a year. I could earn may £10k a year more by travelling but I'm not that keen because it would mean adding at least 2 hours on to my day. I feel that if I could even ask for a few thousand extra I would feel more valued and appreciated. Thoughts please?
