Where 12 weeks shows up
The US Family and Medical Leave Act grants eligible employees up to 12 workweeks of job-protected leave in a 12-month period, which is where 84 days comes from. Note the wording. The statute counts workweeks rather than calendar days, and employers may define the 12-month period in any of four permitted ways, so the calendar span it actually covers depends on the schedule it is measured against.
