Something I needed to read.

There is no promise made today that cannot be erased with an apology tomorrow. Companies go out of business, mergers occur, divisions are reorganized, projects get cancelled, funding is cut . . . and we’re really sorry, but we’re going to have to let you explore other opportunities.

Or maybe your company has grown uncomfortably large (or uncomfortably small); perhaps you have realized that the job you started with is not quite the same as the one you ended up with, and it’s time to move on. Or your spouse has been promoted to a new area of the country. Or you took this last job knowing that it was only a two-year project, and it’s time to look for the next one.

Figures vary, but most experts (and the federal government) say that the average job lasts three and a half years. Which means that the average person becomes a job-hunter every three and a half years, voluntarily or not. And the trend, on average, is toward shorter job tenures, not longer.
