I don’t think I know anyone who has regretted the move per se, but I know plenty who find that being in uniform has downsides as well as upsides, and that the reality of being in uniform has far less flexibility, far more expectation, far less understanding, and far less support than the sales pitch promised.
The pressure will come from both inside and outside - once the uniform is hanging up in your cupboard, you will feel it’s your duty to attend every dogs bum event on the other side of the wing that none of your cadets want to go to, and you will face real pressure to attend from your hard pressed colleagues, as well as your WHQ.
Seriously, every single uniformed member of staff I have known over the best part of 30 years as a cadet, CI, and SI, has faced real pressure - phone calls, emails, and chats about their commitment and motivation - to attend stuff that clashed with children’s and spouses birthdays, wedding anniversaries, and booked holidays.
If you decide to take the commissioned route, I can guarantee that you will be asked to take command of a unit within 18 months, and it doesn’t matter if you’re just started a new job 90 miles away, or you’ve just had a baby, or you’re a single parent with 3 kids under 10, you will be asked to take that command, and you will face huge pressure to do so. You will, sadly, also be directly lied to about the support you’ll be given when you say ‘look, I’d love to take it, but X and Y are happening in my home life, and I just don’t have the time to commit’.
That said, as a uniformed member of staff you can have a disproportionate, positive effect on the cadet experience - you simply have an influence and leverage which CI’s, broadly, don’t get to exercise - the problems, which I’ve outlined above, are not problems with uniform, they are problems which come along with uniform.
