Can you fly domestically in Thailand using only a work permit?

A user's friend has been told she can take a domestic flight in Thailand using only her work permit since her passport is currently with her employer for a 90-day report. This raises the question of whether it's indeed permissible to fly domestically without a passport, relying solely on a work permit. Generally, while a work permit is primarily a document for employment, in certain situations, it may be accepted for identity verification, but this can vary by airline and specific circumstances.
