What does "shift" mean here?
In this video, "shift" refers to "work shift," which is the period of time during which an employee works. You can think of it as a duty period, and it usually refers to jobs that are casual in nature (i.e. part-time or contract). The speaker says "Sunday shift" to refer to the period of work on Sundays. Ex: My work shift was long today. I worked ten hours non-stop. Ex: I work the night shift, so I sleep during the day.
