Regarding Leave, I resigned on the 26th December. I went into the office to drop off a hard copy of my resignation to Fiona and asked about leave. If you have a leave balance left they will either let you take it if leave is available (fat chance) or just pay you the balance on leaving. I just had a request to add my 3 days that i will be owed to my February leave denied.
Been pretty impressed with the process so far. HR Direct turns into a sort of leaving portal. EOS desk in the ESC was pretty helpful too, just get there early as its a busy desk. Main things to note is that Staff travel is no longer DDS. You have to book as normal, then its put on hold until you pay the staff travel desk at ESC. Also FEDEX isn't DDS.
Main thing I need now is a proof of Service to references/security checks for a UK airside pass. I think you only get this letter on leaving EK.
All in all though, the process has been ok...... (so far)
