Question

why are certain jobs seen as unfit for women

Answer 1

There are some jobs for which men are given more preference than women. Men have a stronger physique. They can perform physically demanding jobs better than women. The jobs in which heavy machinery has to be handled are not considered fit for women. A great deal of physical strength and hard work is needed in jobs like mining and mechanics. So more men are employed for such work. More men are employed in the armed forces than women.
