This story in the Washington Post is about federal employment, but I'd be surprised if the same dynamics didn't apply in the states, which will also be coping with the loss of experienced help as the boomers head for retirement.

For decades, the government has hired at lower grade levels and encouraged employees to work their way to the top. But a study released yesterday suggested that agencies are increasingly turning to job seekers from outside the government to fill upper-level jobs.[...]

The majority of the people hired for upper-level positions had substantial work experience and, to some extent, might not be considered as true newcomers to government.

About one-third had worked for a federal contractor, and 16 percent had served in the military and Coast Guard. An additional 23 percent said they joined the government after working in the private sector.
