Sure, and employers actively (and probably to our, as workers, detriment) cause that conflation to make it harder to understand what that worker is allowed to do with their lives. Criticizing the notion of "own time" when the people who effectively have the power, and the greater share of organization (both extant and allowed), perpetuate that notion seems like a less-than-useful use of time.
