Life is unfair.
Some people are sick and others well. Some die young and others live to a ripe old age. Work is unfair, too, particularly to women, but if one waits for the company to change things, a long, fruitless, frustrating and disappointed future likely lies ahead. But that doesn't mean we should accept the current state of affairs. It simply means we should take charge and develop a strategy to change things for ourselves, and in time, by example and support, for others who follow.
