Kelly Shift Pattern | 24/7 Shift Coverage

Very popular with fire departments and emergency services agencies, the Kelly shift pattern uses three teams (i.e. platoons) and three shifts to provide 24/7 coverage. It consists of a 9-day cycle where each team works one 24-hour shift, followed by 24 hours off duty, works another 24-hour shift, followed by 24 hours off duty, then works a final 24-hour shift, followed by 4 consecutive days off duty.

Personnel work an average of 56 hours per week or 112 hours per two-week pay period, and work the same day of the week for 3 weeks in a row and then have that day off for 9 weeks in a row.

Kelly Shift Schedule

When emergencies arise and an employee needs to take a few days off, it can be a challenge finding a replacement to ensure adequate shift coverage while taking into consideration time-off constraints, union, labor and overtime rules, employee availability, skills, preferences, etc.  Snap Schedule 365 employee scheduling software solves these challenges and help companies build smarter schedules, avoid unnecessary overtime, and always know who is working where and when.  Get your free trial now.

Notes– This plan is very similar to the 3 Team Fixed 24 Plan (C3TF24-1). Instead of using a single 24-hour shift, this plan uses the 3 shift system (A, B, C rotation) that is widely recognized by fire departments and emergency services agencies in the United States.


– The US Federal Labor Standards Act (FLSA) compensation cycles are 28 days over which firefighters normally works either 216 hours or 240 hours. Hours worked beyond a base of 212 hours in a 28-day period are considered overtime.

-This plan requires living quarters for the employees to work and sleep during each 24-hr shift.
