Fax delivery of termination notice is valid but violates the requirement for a handwritten signature.

The Supreme Court ruled that sending a termination notice via fax is legally effective and starts the appeal period, but it constitutes a procedural violation. The court found that while the fax successfully delivered the message, it failed to meet the statutory requirement for a handwritten signature on the document. Consequently, the termination was valid, yet the employer's method of delivery breached specific labor law provisions regarding formalities.
