Because of poor performance by DEC's is the reason LCT was introduced.The ones that BS'd their way in ( knew the right people ) failed their first recurrent which was after the probation period. Do some spot checking after 3 months and you can get rid of them ( which did happen ). Could be some of the nay sayers on this forum
DEC is always a possiblity but don't think its in the cards for a while.
