I'm still missing the whole point of this thread. An email from OPM was sent out to all federal employees on the 28th. The FAQs were subsequently sent out based on questions that had been asked by the agencies. None of this applies to ATC, but this also isn't abnormal, either. I get emails from UAL and the union all the time that have absolutely no relevance to me.
If this is a discussion whether federal employees should be returning to the office or stop just riding the pine waiting for an uncle sugar retirement, I must have glanced over those points.
