It's always disappointing to see someone experience sexist harassment on the street, but it's always worse when similar attitudes are coming from the people you have to deal with every day rather than random jerks.
And this is something that women have reported experiencing in many ways when they enter environments that are supposed to be professional. If they're not being turned away from the job entirely due to blanket assumptions about women, it's hardly uncommon for their ideas to be dismissed and stolen in practically the same breath.
That's bad enough when these attitudes and practices exist on an individual basis, but it's also not unheard of for a business' policies to adversely affect female employees and to do so blatantly.
But it's hard for sexist working conditions to get more blatant than what one woman had to deal with before she finally had enough.
