STS, I think he means STN or London-Stansted.
He's wondering if good quality pilots will avoid FEDEX in the future because they'll be forced to fly out of the overseas base, in this case Hong Kong, as a new hire because the senior FO's won't bid it. The quicktake on the main page for Atlas leads me to believe that Atlas expects it's pilots to commute to STN on the companies dime, so why wouldn't FEDEX do the same? I'm sure it would lead to 1 or 2 week trips though, tougher for a married pilot I'm sure.
That's my amature interpretation.
