Sadly, my post-doc is abruptly leaving my group. She has been with me over a year, moved with me from Ivy League U to Big State School, and persevered through a challenging project. She came to me yesterday for our weekly meeting, and told me that her husband set a deadline for her to leave her post-doc and move back to be with him. They are married, but living separately as they each tried to develop their careers. The husband just landed a job, dropped the deadline, and so my post-doc decided to obey and leave. There is nothing I can say or do because family is stronger than anything (to any sane person). My post-doc was clearly upset about leaving, she said that she really wanted to stay but she had no choice.
We set up a timeline for experiments until her departure. She can finish up two papers from elsewhere, and I've agreed to pay her an extra month to cover her time writing. I genuinely hope she can find the career she's always wanted.
