Question about scabies

If you found out you had scabies, would you continue going to work?

When would you know when you were no longer contagious?

The reason I’m asking is my friend works in a nursing home, and has scabies. She has been continuing to go to work and wanted me to hang out with her on her birthday. She said she got rid of them, but I don’t believe her as she said “I got rid of them so I could have fun on my birthday.” She also told me not to tell our other friend who would have been hanging out with us.
