I'm an Electrical Engineer working for a Chinese Contractor in the Philippines, Is it possible for PEE outside the company to sign and seal plans without immediate supervision to the designer while as filipino electrical engineer I'm the one who communicate the changes from the client to our company

I'm an Electrical Engineer working for a Chinese Contractor in the Philippines, Is it possible for PEE outside the company to sign and seal plans without immediate supervision to the designer while as filipino electrical engineer I'm the one who communicate the changes from the client to our company. Will it be considered unethical if my company bypasses me since the PEE can communicate directly to them.
