Final answer:
A 'split shift' means a work schedule split into two separate working periods with a significant break in between, different from rotating shifts or second shifts.
Step-by-step explanation:
The meaning of the phrase 'split shift' is a work schedule that is divided into two parts with a break in between. In such shifts, an employee works for a set of hours, has a long break (often several hours), and then returns to work for another set of hours within the same day. This type of schedule can contrast with a rotating shift work, which refers to a work schedule that changes from early to late on a regular basis and can lead to disruptions of circadian cycles and associated health issues. It's different from 'double-shifts' or 'second shift' which can either mean two consecutive shifts being covered in a single day or, in the case of women, the additional domestic responsibilities they handle after their first shift at work.
