"Work environment", "culture fit", etc. are usually just euphemisms for "your boss."

As in, if you're interviewing and an applicant says they left their previous position because it was a "bad work environment" or a "bad culture fit"—they're saying they had a horrible boss. And if someone says they're looking for a place with a "better work environment," what they're looking for is a place where their boss will defend them against outside interests, won't micromanage them, won't force them to waste their time on work that won't get used, etc.

I suppose that the people saying this may not even realize they mean this—most people don't put much thought into how much of the everyday experience of "work environment" is controlled by what your manager does or doesn't do for the team.

But this is why people will describe places that might seem cloying and unappealing as having a "good working environment": they mean that you're likely to work under someone that knows what they're doing.
