If the employee number is a numeric field, you could randomly generate a number in a range and use it as a replacement for the original number. Keep in mind though that if the employee number is a primary key, you must generate unique replacements and that gets tricky. If the idea is to protect identity, you may want to look at masking other attributes like first name, last name, address, email, phone number, etc., By masking many attributes you make it harder for anyone to know the original identity.
