Hygienist, our hijack in the profession only for personal gain they do not give a damn about people‘s health. Otherwise, they would not be doing a cleaning in five minutes when it suits them (Because they have to leave) or stretch it to an hour when they do not want to work. So stop pretending it’s not about money because it is! 
They are camping instead because they make more money and they do not care about the patient. They just do the bare minimum for pay barely clean the people properly.
