Asking a coworker about his health issues
Your workplace offers plenty of opportunities that can get you sued. Being aware of those factors is critical to avoid future headaches. So, things like mean comments, rumors, or unprofessional reactions can all lead to an unwanted lawsuit.
Asking a coworker about his surgery is placed in the same category. You just can’t do that, no matter if you’re the boss or not. Even if you think that the comment you made was just a joke, your coworker might feel otherwise. The best thing to do is keep conversations cordial and remember that you’re at work… so any non-related work discussion doesn’t belong in the office.
It’s easier to keep your personal life, well, personal.
