tbh that's probably not all that unfair -- whoever created the timelines should have already accounted for it, and if the timeline was created long enough ago (because the project is sufficiently long) before the move was known, there should be significantly more than two weeks buffer included for issues exactly like this. Of course, it's also that person who should inevitably be held accountable for the fuck-up (unless the move was sudden, in which case it's the fault of whoever initiated the move.. perhaps the C*O :)

At least in my mind the only time its the fault of the employee himself only when they slip their own agreed-upon schedules, without warning or reason
