If you switch between jobs once every five years, then 20% of the time you've been at your current job for under a year. That's what that 20% measures—not people who left in under a year, but people who left within the last year (which is easier to measure). If that rate goes up, people must be switching jobs more often; if it goes down, people must be switching less.
