But that is also the default mode. It is not the best way of doing things, but most employees do have to deal with managerial quirks.

If I will be having to deal with those quirks anyway, then the guide is helpful. Otherwise I am learning via trial and error. Sure, ideally the quirks would be fixed, but that is not a likely event.
