Key legal question
Whether the notice period was suspended during illness days that coincided with a holiday and a semi-holiday.
Extracted holding
Yes. Article 336c CO does not exclude sick days because they fall on holidays; the notice period was suspended for 24 and 25 December 2006.
Extracted reasoning
The statute makes no distinction between working and non-working days, and its purpose is to give the employee a full notice period to seek new employment. Excluding holiday illness days would contradict that purpose and the legislative text; the lower court's reliance on a 'semi-holiday' concept lacked a legal basis.
