I want to ask my employee to poop at home
Is there a reason why they can't just poop at the office?
No it's not that. It's just I couldn't enjoy taking a dump in the toilet with that person around.
You shouldn't tell employees to use the restroom at home while you allow yourself to use it as you please. You'll be seen as a hypocrite and your employees will look down on you. Try setting up a bathroom schedule if you feel you need privacy.
It's fine I'll go to the bathroom when I have to.
That would be the normal thing to do. You can't tell employees that they are not allowed to poop at work. It is probably illegal.
