A min-max contract, sometimes called a bandbreedte contract, is a form of on-call agreement that combines a guaranteed minimum number of paid hours with an agreed maximum cap. The employee is always paid for the minimum, even if no work is offered, and may be called up to work additional hours up to the agreed ceiling.
The contract must specify both the minimum and maximum clearly. Dutch case law requires that the maximum remain reasonable in relation to the minimum, usually not exceeding roughly one and a half times the guaranteed hours, to prevent circumvention of the rules that protect on-call workers. Hours worked above the maximum must either be refused or offered as a contractual variation.
Min-max contracts count as oproepcontracten under the Wet arbeidsmarkt in balans. The four-day advance-call rule, the three-hour minimum-shift rule, and the obligation to offer a fixed-hours contract after twelve months based on average worked hours all apply.
