Tough call. I think you hit the right one though with plumbing. Carpenters and electricians depend too much building booms. Plumbers remain in demand because plumbing wears out. It is hard to predict the long term viability of any job. Right now health care is in demand and growing. A lot of people think that is a guaranteed job forever. It isn t. Health care is growing because of the baby boomers who are aging and needing more care. Once we (I m 58) all die off in 30 to 50 years there will be too many hospitals. nursing homes and health care workers. Computer careers were thought to be indestructible from about 1990 to 2000 but that was the combination of year 2000 reprogramming and building the internet. In the 60 s it was aerospace workers and in the 70 s it was petroleum engineers. This is just another recession, like all other recessions. It will end. Choose a career you like. It is just too hard to predict the future.
Any job working for the local council.
