I don't live in the UK, but my country is not too different so I think it's okay to ask the question here.
I always thought my salary is good, but lately I can't help but feel like, maybe, it isn't. But I compare my salary to other people's salary without taking into account that they might work more hours than I do. Anyway, I work 34.5 to 35 hours a week (Monday to Friday) and I earn about £37k annually. My salary increases annually with about £1.2k, and in 3 years time it'll increase by £1.2k PLUS about £4k annually. Making my annual salary £41k PLUS a yearly increase of about £1.2k.
I should probably also mention that I work in an NGO, so I probably don't earn as much as I could earn if I worked elsewhere.
