Key legal question
Whether the oral dismissal of 2004-05-24 was valid despite no written form being agreed
Extracted holding
The dismissal was valid because the parties had not agreed on a special form; oral notice was sufficient.
Extracted reasoning
The cantonal findings bound the Federal Court on the absence of a written-form clause. Without an agreed form, termination of employment does not require writing, and the oral notice was received before the employee became unable to work.
