The President of my company tells me I need to "behave like a good wife" and "I want to see you working side by side, like sisters" with other female colleagues.
Are these types of comments illegal? Or just inappropriate?

Are these types of comments illegal? Or just inappropriate?

Neither (unless the context of the comments might make them inappropriate). What's the problem you have with the comments?

When I read the title, I figured it was about something the POTUS said. "So, what else is new?", I thought. :)

Why would he tell you this? Have there been problems at work?

What was the context of these comments? Regardless, illegal doesn't seem to fit for sure. Nor does telling females to work together like sisters seem inappropriate to me either.

Actually "work like sisters" to me brings up images of scrapping cats (probably not what he has in mind!). It would be better for him to say "work together like professionals," but I see no disrespect in that comment. However, I don't understand the "behave like a good wife" comment - does he mean "shut up and listen?" (some people may think that's what a "good" wife does), or does he mean "support the decisions made by the men?" or does he mean "be a team player." The first two interpretations are demeaning, but in my opinion do not rise to the level of harassment that would make it a hostile work environment. In any event this boss could use some sensitivity training.

... The first two interpretations are demeaning, but ... In any event this boss could use some sensitivity training.

If his (assuming the boss is a he) comments could (in context) mean one of the first two interpretations.

His comments aren't appropriate for work, but I don't see any legal problem for him.

By any chance do you and your female co-workers talk too much, too loudly, and reveal too much about your personal lives? And argue, or even fight?
Then any one of you is in danger of losing your job. Worry about that first.
