I’d like to know how the receptionist at my office still has a job too. She barely wears any clothes, sleeps at her desk for hours, and is a total nut job

what does your organization do? What does that person do? That is a big impact on the answer. Also that person may in contact with HR and on a leave of absence or temporary leave. HR won't disclose that for privacy reasons.

Sadly these are strange times we are in right now. I can't believe the help at restaurants telling the owners when they will work and making them close on weekends. That behavior just made one of my favorite places close permanently. Now they don't have to worry about working weekends. They can have the whole week off. Personally I think your new person should be let go. If course in the meantime I am sure that means you are not only doing your work, but hers too. 😠

Without knowing the work environment, it's hard to say, but I for sure would keep a record of it and if there ever comes a time when you get written up for absenteeism, I'd bring it up.

I'd say to focus on your punctuality and authenticity.

He/she obviously has a special arrangement with the boss.

Depends on how generous his boss is feeling

Depends on who it was.

You friend is still looking for another job snd interviewing.

Most likely nepotism
