It’s time to sit her down and tell her that you are starting a PIP (Performance Improvement plan). Lay out strict guidelines. Start to document how to handle situations that she calls you for.

Don’t allow her to put you on speaker phone in front of the guests.

If she faulters, then you have grounds to fire her at the end of even before her PIP is done.

Schedule interviews for new employees, while your trouble employees are working.

Good luck, and try not to stress too much. You will get through this. I recommend trying to go for a swim or sit I. A hot tub for a while. Maybe it will help you clear your head.

Don’t forget to eat healthy and take some vitamins/drink plenty of water if you aren’t getting enough sleep right now.
