Blue collar jobs such as plumbers, carpenters, nuclear power reactor operators, divers, conductors, firefighters, electricians, and aircraft mechanics. These are high level because they do not only require manual labour but require practice and specific abilities. These are skill based jobs and require some level of education experience too. They do not demand degrees but require some training or shortterm courses from any trade organization or apprenticeship program. Only trained and talented professionals can accomplish high tier blue collar jobs. One of the most reasonable parts of these jobs is that they provide employees with good working conditions, reasonable salaries, job security, and several other perks.
