All monitors should attend a special course in handling seniors when tempers are up. We are more fragile, and more apt to lose ourselves due to meds, and normal aging changes to the brain
The BOD can probably easily find a consultant to train the staff. Putting one’s hand on someone’s chest is taken as a hostile gesture by most people. A person has a right in self defense to quickly remove the hand, usually by shoving the offending monitor back. If the monitor with hand on chest of senior becomes offended into anger, the monitor can easily scrunch up their hand grabbing the senior tightly by the shirt and set them up for a blow with their other hand. After that you have a broken senior and a big time lawsuit with some jail for the monitor. Violent crime committed to a senior is punishable by double the regular penalty for this assault.
In addition, a monitor should not take seriously the words or actions of an out of control senior if the monitor acts as security. Working in a senior community is just more difficult, and one has to curb their emotions.
