I’ve been in my job for a while and don’t feel there is any scope for me to get promoted so I have been weighing up my options. How do I broach the subject with my boss?

It is quite normal to find yourself in a job with seemingly no avenues for progression. So what are the options if you are in this situation? First, you need to be clear as to whether you actually want the hassle of more responsibility. There is no shame in reaching a level you are happy with and electing to "stick" there, avoiding the added complications that promotion might bring.
