She is losing a home and likely what would be funding her new home for the cross nation move she just made for you and your company is bugged she didn't stroke their ego in an email?

"Dear Sam,

I am so grateful to be here and to work for such a meaningful and impressive group. Unfortunately my home is currently underwater. While it pains me to leave the team so fast and I would rather stay and work because this is my number one priority it is imperative I remedy the home situation. I need to ensure that this home is able to be sold so I can complete my transition.

Please accept my deepest regrets. I will be available in a week. Thank you for understanding. I am so blessed to work at such an incredible company.

All the best,
Rachel"

Such a joke that people expect this. I get companies need to run but lets be frank no one cares if she isn't there. She is not going to negatively impact anything. Sounds like you need to look for a new job.
