After working half a day today, I was advised that my position is now considered "non-essential" (I think "non-time-sensitive" is a more accurate if less wieldy term). I'm on PTO this afternoon and probably at least tomorrow, which doesn't bother me at all. In fact, it is probably preferable to going all the way to HQ to do not much but wait for questions that aren't coming under the current circumstances.
For now, I'm treating it as a long weekend. If it goes much into next week, I may want to discuss options with my company.
