Ok. In response to some private messages, I dusted off some old notes on the area. This is basic summary info which may be incomplete and possibly even inaccurate and is not to be taken as legal advice. If you or someone you know is involved in this kind of situation, you should contact a practicing lawyer in your area regardless of what it says here.
In the US, if an employer has employed 50 or more employees over the course of the last year AND the employee in question has worked a full year for that employer AND worked 1250 hours for that employer during that year, the employer is required to give a certain number of weeks unpaid leave for maternity (or paternity as long as you are actually taking care of the child/mother and not going on vacation).
When that employee comes back, the employer has to restore the employee to the same OR SIMILAR job. However, if that person is a "key employee," the employer can hire a replacement and does not have to restore the employee to the old job. This exception is intended for special or high-level employees (usually with income in the top 10% of the company) that the company cannot do without during the leave period.
So it looks like the issue would turn on whether her position was a "key" position that they employer had to fill quickly. If she had high-level international responsibilities, then it MIGHT be a "key" position.
Of course this isn't even being brought in a US court anyway. :\
