Babysitting the babysitters (revisited)
Let's say you need a plumber.   The pipes under your sink are leaking and there's a ton of water on bathroom floor.

So you call up a plumber you know to be a competent worker---very skilled and knowledgeable in his trade.

However, this guy has an issue with punctuality.  He can't be relied on to show up when he promised to.  And often he doesn't show up at all when scheduled.  Later he may apologize and tell you "a family issue came up suddenly" and that he had to take care of it right then and there.
And, unfortunately, this seems to be a regular pattern of his.

Hence, you're stuck with the formidable task of having to badger someone you're dependent upon, in a somewhat parental manner.   In short, having to assume authority over someone who's suppose to have an authority over you.

Much like a landlord who fails to make repairs or maintain the residential building.
Or your supervisor at work who fails to mention you've been given an extra assignment that particular day ...then, when you come in the next day, you find yourself being penalized for "negligence" and "insubordination".  
It's like you have to "boss the boss around" to get them into action.
These sort of situations are among the worst kind of precarious ones to be in.  Because you don't wish to risk offending someone who's "over you".  Yet, if you DON'T say or do anything certain problems stand to never get solved.
