Carrying a firearm for the purpose of employment, such as an armored car driver, armed security and other similar jobs is regulated completely separate from regular concealed carry. In fact having a concealed carry permit does not allow you to carry a firearm for employment purposes and having passed ACT235 does not allow you to carry a firearm while not working.
