Ok, what is the most popular shift length?
When shiftworkers are asked to focus on shift length and it’s effect on time-off alone, most shiftworkers prefer 10-hour shifts over either 8-hour or 12-hour shifts. Unfortunately, many shift work operations cannot use 10-hour shifts well because a 10-hour shift does not divide well into a 24-hour day. If level coverage is needed all 24 hours in the day, it is very difficult to get that coverage with a 10-hour shift schedule. For more information on this subject, see: 10-hour shifts, Shift-length Issues, and Shift-Schedules.
