I remember back some years in my years as a junior civil servant.   Every six months we had mandatory training courses to attend – back in the day it meant literally leaving the office, heading off, a few at a time, to another site miles away – all to be given the latest presentation – death by powerpoint.  The cost must have been dreadful and it meant we were missing from duty for much longer than was sensible.  These days they are so much better at retraining staff.  All the career focused e-learning courses are available and each member is encouraged to choose one a year to really help personal development.  The mandatory online training is much better too.  I know the anti fraud one I last participated in has stuck with me for a long time and I recall the salient points very regularly whenever I deal with trades people!
