In the article, employers preferred to hire men to women. They would rather hire childless people, and they also prefer people who can work as many hours as their bosses would like.
Many of us make assumptions about people, sometimes knowingly, and sometimes not. We do this based on our experience, conventional wisdom, others' opinions, and just plain ignorance.
It seems that despite efforts to change employment law, actions sometimes change before attitudes. And if attitudes don't change, then the law is limited in its reach. If the law doesn't always change minds, what does? I have a few ideas, based on what's helped me overcome a few judgmental ideas of my own.
Popular culture. If a person doesn't come across a female boss in real life, they might do so in the entertainment they watch or the articles they read. When it comes to shows, it seems almost everyone has an opinion. Even if the people who consume the media are still ignorant (see recent Cheerios commercial), at least the people who break media barriers get people talking about these issues.
Exposure. Of course, people tend to self-insulate. But unless they live in a cave, most people will meet a variety of people in their careers. The more they give themselves opportunity to surround themselves with different types of people, the more they will be able to appreciate people as they are rather than expecting them to conform.
Asking questions. You can't understand how another person works or what motivates them until you ask. Once a friend with a different political perspective asked me about my political views, not with the goal of changing them, but just so she could understand why people thought differently than she did. I've seen so many ugly arguments where people put anyone who thinks or acts differently into a singular mode. This can happen just as easily at work, where employers might assume that because an employee is female or young or Middle Eastern, they automatically want x, when that might not be true at all.
Do your homework. I don't think it's too much to ask that employers or workers use facts to back up their opinions. If you think that a male childless college graduate workaholic is the best candidate for your position, do you have any numbers to prove that? The more information you have, the more advantage you have over those who form opinions based on short-term needs or emotion alone.
What has helped you overcome previously held assumptions?
