In my counseling practice, I work with lost of people 50 and older who found out that losing their jobs was really a prison break. But it is just a matter of figuring how to make that happen. In today's Free Agent Economy, and it addresses just this topic. None of the above. The most important thing is how well the tasks of the job and the opportunities match their long-term goals.
Salary is probably the least important, because that happens over time rather than right away.
The most unhappy people I find one year out of Smith are the people who took a job that didn't sound like fun because the salry was irresistible. Anyone who is doing that should be protected from the vagaries of the job-market shifts. The most important thing for a job seeker to remember is that they are applicants, not supplicants. It is important throughout your life to put yourself in work situations that really fit who you are. And be constantly ready to move when that is no longer true.
