So is it possible to be a fast-food worker or an office worker and then go on a 5 week course and come out the other end proclaiming to be an electrician. In addition to that should you be allowed to do a 5 week course and immediately go self employed. Is it safe to do a 5 week course then immediately be let loose on the public. In my opinion if you insist on doing a 5 week course it should be compulsory to work for a company under a competent electrician for at least 3-5 years before becoming self employed. 5 weeks!!! It took me longer than that to learn to swim.
