Is the measurement that they’re getting the results, or is it that they aren’t working extra hours? “Getting the results from the majority of the people the majority of the time” is exactly how I’d expect an executive to handwave employees burning out due to the kind of environment we’re talking about. Not everybody is going to manifest visible problems at the same time, so it will just look like a handful “not working out” every once in awhile, which is to be expected.
It could describe a healthy environment equally well… But my point is just that your formulation (“Results from the majority of the people the majority of the time”) doesn’t seem to me to have the ability to distinguish between a healthy and a toxic environment.
