Talking about work during a business dinner does not equal hours. Thinking about work ideas after hours does not equal hours. Fostering a business connection does not equal work hours.
And if they do, then I get to count stressing in the shower, arguments in my head while I go for a walk, ranting to my partner about work problems, and keeping in touch with former coworkers.
Objectively, it sounds like it's an innocent tradition and a healthy charity.
Subjectively, it's tone-deaf af, when the rule-makers perform superstition for such a massive world-changing problem. Basically "thoughts and prayers."
