You are not a doctor. You don't play one on TV. You should not be placating the Government to do so now. Only you can be held liable for any adverse events to your employees. The Government and CDC will allow you to register these side effects though. No medication is safe for an entire group of people. Not even asprin. So stop before you start and make them (FED or State) come after you. Then join class action lawsuits for remedy. Easier said than done. But you will still be able to look in the mirror after all is said and done. Also, congrats on building your company that created this situation. Good Job!
