Having the chance of acting rank is a lottery in itself. Many cases of acting rank are handed to people just because the post needs filling whilst the 1st TO is OOA etc. I've known Cpl's to get acting rank after less than 2 years seniority, are they really ready for promotion? Anyway my view is that 25 people out of circa 700 to be promoted is a joke, ok it's all down to service need but MANY people are currently pee'd off in the trade. Here's how I see it.....I work in careers atm and only 20% of the ITT (into training targets) have been met so far this year, NO ONE IS JOINING AS AN ICT TECHNICIAN!!!....this can only mean that SAC's won't get their tapes as there is no back fill through Cosford, I honestly think it's going to get worse before it gets better.
My bold, this is more of a problem than we realise, when promotion is so slow and limited in numbers then what happens IMO is this: The best try their hardest and do secondary duties etc and maybe half of them get promoted the other half take it as a slap in the face after all their hard work and maybe don't try as hard the next year "what's the point?". The other 90% of the rank/trade know that the chances of getting promoted are so slim that they don't bother going the extra mile/volunteering etc. Such low numbers off the board don't act as an incentive to try harder but more a "don't bother going the extra mile as it won't help you".
All just my opinion I know and I realise it tars people with the same brush and that people will always say "not me!" but I'm starting to pick it up in more and more peoples attitudes.
