It's the EK way - I asked specifically at interview if DEC's would be coming to EK and was told categorically 'no way, it's been proven to be too divisive and has no real benefits' - guess what, the first DEC turned up about a month and a half after I did! Coupled with the ' sorry, you can't have the accelerated command we promised at interview' it was a pretty big kick in the nuts.
EK promises are worthless - even if they're written down.
