The reception area in the Emergency Department of our local hospital has long displayed a prominent warning sign, to the effect that "Physical or Verbal Abuse" of hospital staff will not be tolerated. Likewise, there has always been similar signage at most of the doctor's clinics around the district (long before the COVID-19 virus was ever heard off).
My brother in law was a long-serving paramedic in the ambulance service, and spoke of how he and other ambulance officers often physically attacked while at work. The problem was so widespread that one of the pre-requisites for being an ambulance officer was described as being both physically robust, together with a definite mental hardness. Although he, in many ways, fitted the bill (particularly as a former rugby union player), the stress finally drove this person to drink. In order to help break his addiction to alcohol, my BIL had to get himself transferred onto less stressful work.
Why anybody would abuse others who are only trying to help them is completely beyond me!
