Alternate

Here you define how a series of shifts should alternate.

Example:

• Erna and George work in three shifts. If the first series of shifts includes 10 am then the next series should include 5 pm and the third series should include 11 pm.

• Rossi works in two shifts. In the first series, all shifts must include the period between 9 am and 11 am. In the second series, all shifts must include the period between 1 pm and 4 pm.
