The way I became a DBA was possibly unusual. I was classified as a 'SQL Developer' at a large international company, and that placed me in a certain salary range that was below that for a 'Database Administrator'. So at an annual performance review I asked my manager to change my position classification, which he did, and that placed me in the higher salary range for the company.
At another point at the same company I felt I needed a higher salary, so prepared a summary of all the functions that I performed for the department, asked my manager for a meeting, and presented my summary along with my requested salary level. His response was 'OK, I'll handle that'.
And a third time, after I had taken an early retirement package during a down-sizing, I was contacted by my manager and asked if I would be interested in returning to my position. Again I was able to negotiate a very nice salary increase and unlimited unpaid time off for returning to work as a contract employee.
My conclusion is that sometimes you need to take charge of things for your own benefit. You can take your own steps up your ladder.
