What is a 9/80 schedule?

Eighty hours over nine working days in two weeks instead of ten, so every other Friday (or another weekday) is off; a 4/10 is four 10-hour days with one day off every week. In the postings' own words: AST SpaceMobile, "You will be working shift 2 which is 5:30 pm to 4 am Monday through Thursday (4x10 schedule)."; Northrop Grumman, "This position will work a 9/80 schedule, with every other Friday off.".

Is a 9/80 schedule offered for every role?

No: the postings say it role by role. Each role listed here names a compressed week in its own posting, and an employer's other roles may work a standard week or shifts.

How is this list made?

We read every open posting's text on the space employers' own job boards once a day. A role is listed when its posting names a 9/80 schedule, four 10-hour days (4/10 or 4x10), a four-day week or 12-hour shifts, by the same rule our research on shifts, weekends and travel counts with.
