Subject2load has it exactly right. And not only for front-line staff. I sent an email to EK via UK website contact section to ask what the EK policy is for fast track for Golds departing MAN in Y. This was the commendably rapid initial response:

"As mentioned in our website, Fast Track vouchers are available at most airports around the world, to help speed your way through airport formalities.
Upon review of your query, we have established that we need additional time to fully coordinate this matter. We apologise for any inconvenience and expect to respond to you shortly."
