These days, even the renowned Mayo Clinic in Rochester is scrambling to fill holes in its nursing staff as baby boomers continue to retire.
Not that the folks at Mayo are particularly worried.
"We've seen this before," said Pam Johnson, Mayo Clinic's chief nursing officer. "It ebbs and flows. Some years we've hired 40 or 50 and some we've had up to 500. This year ago it will probably be somewhere in between."
It didn't help that pension benefits will get calculated differently beginning in January, and every time benefits are tweaked, Mayo seems to experience a surge of retirements. The clinic's leaders say they saw this one coming, too, but it's made a hard job harder.
Well-managed organizations routinely plan for growth, of course, but it's increasingly obvious that figuring out who's planning to leave via retirement is just as important.
As Mayo Clinic can attest, work force planning is a job that you work at every day.
Linda Hamilton, the president of the Minnesota Nurses Association, describes the age distribution in nursing as "a very U-shaped curve," with lots of nurses early in their careers and then another big group nearing retirement.
"The nurses 15 years older than me, the ones now in their 70s, their income was usually supplemental to their husbands'," Hamilton said. "That's not true for my generation."
