Taking DEC trainers (elect) is an admission of defeat.
For whatever reason, MM can't make the job attractive enough for those in the company to want to do it. Personally, it's about the lifestyle. The extra money would be handy but something better than min days off and being forced to end up a TRI/TRE would make a big difference. (I know they say you can stay TRI-AO for a while but they still expect you to go the whole hog eventually).
