Why would you search for a new job?

From talking with my friends in the recruitment industry they suggest the 5 key reasons for why people look for a new job are:

1. To earn a bigger salary
2. Have a balance between work and other pursuits in life such as family, hobbies and sport
3. Difficult relationship with their boss
4. Career Development - in some cases climbing the corporate ladder
5. A mismatch of values between self and the culture of an organisation.

Have the reasons really changed over the last 25 years? Certainly we didn't hear 15 years ago a balance between work and life was a reason. Perhaps it was, but it was considered not an appropriate reason to give at a job interview because the applicant feared they wouldn't be taken seriously.

More money has always been a key reason for moving into another role. If you feel you are not being paid your worth it makes sense to do some window shopping to see what the competition is offering and whether they offer the same or bettter conditions. However, do you really say this at an interview and risk the interviewer thinking you are only there for the money.

I think for many of us the reasons why we look for another role are more complex than a single reason alone. It can be built up over time and can start from an innocent exchange with your boss when she didn't listen to your great business idea, compounded by organisational restructures, new work rosters and little investment in training.

What are your views on the reasons why you would search for a new job?
