For example, with the new technology emerging in every day, electricians will be more in demand to install the computers, telecommunication systems and other equipments. There are now many new robots being even developed and other automated equipments which require a complex wiring system and installation procedure.
When the old electricians retire, due to lack of physical fitness, they leave space for the new ones, so there will always be a space for new electricians in the market. Job market will be created especially in those areas which are developing at a faster rate than others.
However if there is a fall in the economy of a country, there will be a gradual decrease in the job opportunities for electricians too. They can therefore apply in other countries which have a good economy rate and are developing at a good pace.
