The point in all this is to say – that at some point his employers may conclude that he has no future there (or no near future) and they may decide to drop him. That will mean a loss of medical coverage. Once again, it's tragic that in the flawed American system one's access to health care has all too often been tied to employment. This has made people vulnerable and in some cases it has effectively enslaved people to their employers as they live in fear of losing coverage. This is all the more true in the case of those that have chronic conditions and need regular care or rely on expensive medications. One can safely say the whole system is a mess and yet the primary driving factor of that mess – is the profit system. It's all the more egregious in the context of human health and suffering as it preys on fear and desperation.
