<h3>What is
on-call worker?</h3>
An on-call employee (oproepkracht) works only when you, the employer, summon them. You and your employee have agreed on this. There are various forms of on-call contracts, each with its own set of rules.
An on-call schedule (or on-call shift) is a timetable that guarantees the appropriate person is always accessible, day or night, to respond rapidly to events and outages. On-call doctors in the medical field are expected to respond to medical crises at any moment during their shift.
On call is a vital duty among many IT, developer, support, and operations teams that provide services that customers demand to be available 24 hours a day, seven days a week. Team members rotate via an on-call cycle, providing coverage around the clock or solely during normal business hours.
