Can you charge out as much for a journeyman as a master plumber?

Many master plumbers send out employees who are not master card holders and still charge the same rate. In locations that do not require an employee to have any type of license ( NYC for example) a Master plumber can hire over 500 employees and charge any rate they want.

It is not uncommon for the franchises to say "we are sending a technician" out as they are trying to get over licensing laws and are able to charge master plumbers rates for non licensed /non skilled help
