Whether or not my supervisors think they're taking advantage of me is a different matter, and one that is largely irrelevant to me.
If I'm not, then that's the fault of my own behavior and isn't related to whether or not my employer is taking advantage of me. If my employer actively prevents me from being able to live a healthy life, that's a different matter entirely -- but I wouldn't be working there for long.
"Loving" is not binary. There might be room to love it even more, especially if they stop taking advantage of you.
If it changes, then I no longer love my job...
"In one study, participants who read that an artist was strongly passionate about his job said it was more legitimate for the boss to exploit the artist than those who read the artist wasn’t as passionate. This finding extended to asking for work far beyond the job description, including leaving a day at the park with family and cleaning the office bathroom."
These are regular people taking part in a survey, saying that it's OK to make a passionate person cancel a family weekend outing TO CLEAN THE OFFICE BATHROOM.
If I were required to do that sort of thing, then I would consider that being taken advantage of, and I would stop loving the job.
