The job market, for the most part, wherever you live, is never a secure thing. One day you could be working in your office, fielding calls from people interested in hiring you to refer them to the best wastewater treatment equipment system technician for instance, and the next day you could find yourself in a market that doesn't have too many painting companies still in business. You never know when such a day might come but it's always good to be prepared for such a day. Who knows, you might be a certified part time bookkeeper in Mississauga as well as a notable talent agency. In that case, you're pretty much covered for when that day you need a new job comes because you will already have skills and qualifications in two different fields.
Not everyone is that lucky though. Some people spend their whole lives in the same field. Or have only gone to school for one certain skill. If that day comes when you have to quit your job and live off saving or government support, you might regret not learning another skill. So, why not take charge now so that you never have to worry about not being able to work in a different industry? It is never a bad idea to have knowledge or skills in another trade or career field. That way you will have something to fall back on if you lose your current line of employment.
Being knowledgeable in a different trade or having skills that could translate well to a new line of work is an option worth having in your back pocket. If you don't know more than the trade you currently work in then learn a new trade. There are plenty of courses out there that teach a variety of different trades.
You can take a class on how to repair car engines, on how to handle tamper evident seals, on how to build woodworking equipment, on how to put together computers, or how to install satellite dishes. There are plenty of trades out there in which you can go out and learn the necessary skills in order to get a job in one of them.
Like we said before, you just never know when you might need a new job. The economy fluctuates on a daily basis and sometimes the safest career that never seemed in jeopardy before could one day turn upside down and be completely unstable. If you find yourself working in that field when that day comes you're going to want to be prepared if you have to go out and find a new job. Having skills in a different trade would be the best way possible to prepare yourself if that situation ever arises. If it doesn't, you can always be happy that you learned a new trade and turn it into a hobby.
