>>15031812Accidents in the workplace happen sometimes anon. Do not be overt, just enough power to jar. Make it look like a bump. If it continues, a second at 1/3 power into a wall. Shoulder leads, power through legs. You want them off balance upward & backward. When no one is around of course. Never a door jamb. The second gets the message across. Never had to escalate. Stubborn cases require a yearly reminder. Good luck.
