Each calendar year, you can choose different sources and targets. However, in January it is only possible to sell holiday leave. During any other month of the calendar year you can make whichever choice you want. But they always apply until 1 January of the following calendar year.
In order to process the choices made in the payroll system, the Individual choices model has a monthly closing date for submitting your choice. This is indicated in the module. After closing, the Individual choice model is opened up again around the 24th of the month for the next calendar month.
The Individual choices model enables you to trade and exchange your terms and conditions of employment. However, the starting point is that the original value set in the standard package of terms and conditions of employment does not alter. Changes may occur for individual staff members within this package of terms and conditions of employment, but the total value remains the same for each employee. Some employees may, for example, opt for less holiday hours entitlement in order to finance a new bicycle under the bicycle scheme. Some may opt for more holiday leave hours entitlement in exchange for a lower salary. When expressed in monetary terms, however, everyone maintains the same value.
The Individual choices model Regulations (pdf) forms the basis for this scheme. This web page contains practical information with a reference to the applicable articles in the regulations.
