- 2025 July 1, Kimanzi Constable, “What is a micro-retirement? Inside the latest Gen Z trend”, in Fast Company‎[1], archived from the original on 9 July 2025:Gen Z is using micro-retirement to avoid burnout, find greater fulfillment in their work, and enhance their overall well-being. However, it’s not just Gen-Z: According to a survey from Side Hustles, 10% of workers are considering taking a micro-retirement and 75% thought employers should offer micro-retirement policies such as unpaid sabbaticals.
(metric units) One millionth. ‎micro- + ‎gram → ‎microgram

Usage notes

[edit]

(one millionth): Officially, micro- is abbreviated as µ- (the Greek letter mu); for example, one second is 1 s, so one microsecond is 1 µs. However, for many purposes this is inconvenient, so writers often use either u- (for its similar appearance to µ-) or mc-, producing, for example, 1 um (one micrometer) and 1 mcg (one microgram). See also mcg § Usage notes.
