It follows from the European Court of Justice’s statements in the so-called Jaeger case (Case C-151/02) that the requirement for “compensatory rest” entails that an employee that has had less than 11 hours continuous rest shall have the corresponding number of hours compensated immediately following the work period. In other words, the reduced rest shall be compensated hour by hour in the next rest period. For example: If an employee has worked for 15 hours, the requirement for ”compensatory rest” entails that this employee shall have two hours of compensatory rest in the next rest period, in addition to the ordinary rest of 11 hours.
