I think you mean that it is not easily quantifiable or provable with evidence. That does not mean the statement is not true and accurate.

No I mean it's a subjective view from the boss that doesn't mean anything.

She could have said that they were procrastinating, or could have said that they were consistently tired and whiny about it. Or maybe these particular women did not want to work all their weekends away and complained about it. Or it could mean they weren't cheering at the beer pong event. Who knows?

I'm just saying that 'women I hired lacked energy' is the kind of blanket statement that overgeneralizes and that fans the vicious circle she described as damaging below.
