I get to work, my employee left me a note on top of the time sheets that said: “Here are these (time sheets) for you to also check to make sure we didn’t steal (underlined twice) from you!

This was after a $2k bonus and PTO for Xmas eve (and of course Xmas).
I asked about it, she said she didn’t feel appreciated and not trusted because I asked to see the payroll time sheets.

I run a small private practice mental health office. I’m used to dealing with emotional people, but they pay me to help them with their emotions, not the other way around. So I was livid and told her to go home and come back to work on Monday and let me know if she still wants this job.
What would you do?

*the $2k bonus was the second yearly bonus she received. I also used my personal money to help with her dental emergency over the summer (on my vacation.)
