If an employee is adversary toward the company, the trade off needs to be made no matter how much valuable the employee's work is.
This is a non-issue tbh. She wants to leave. Company wants her to leave. They both agree to part way because the premises are fulfilled (i.e. company can't meet her requirements).
If you want to get technical, I'd bet her employee's status is still in tact for 2 weeks; she just doesn't have access to laptop and etc.
