I can echo this.
When I had my cushy workshop job, perma days, I could devote some time to cadets. It was enjoyable. And for my own personal development… It contributed to being promoted.
The vast majority of technicians are employed on squadrons. As I am now. I work week of days, week of nights. The Friday in days is until finish. Which has been 2100 before after a 0700, followed by weekend work if required.
I now have a son. A son who was very nearly taken from my wife and I in his first few months of life.
In the year since he’s come home, I’ve had a total of 200 days away, be that on courses, Shader or other stuff.
Half the year, I’m on nights, unable to attend the squadron. The other half I’m on days. Having the responsibility of being an NCO, which means I’m often last out.
Do I want to spend my evenings looking after someone else’s children after I’ve spend over 50hrs away from mine? Absolutely not.
I do try and make time, because I genuinely enjoy it. The cadets enjoy it. I bring a perspective that our squadron staff don’t have.
But as to why many don’t do it? We are getting fragged. My squadron has 60 empty and gapped posts. Of which half of those are NCOs. We simply do not have the manpower for people to take the leave they want and in many cases, need.
I am worked from 0730 until 1630 most days on pure physical work. Next shift is in at 1630, I then have hand over and paperwork completion to do.
You then factor cadets marching through camp in the mornings to breakfast. Screaming cadence as they march through accommodation sites. I can tell from my own history in SLA, when you’re trying to sleep and cadets are marching through, waking you up… And then clogging lines in the mess when you need to eat and get back to squadron. It doesn’t foster a positive look from the serviceman’s side.
I’ve had adult SNCOs tell me to do things on station such as make way for cadets in the mess, when I was a phase three trainee (SAC with over 4yrs service at this point), I was shouted at by adult staff for not marching correctly. Likewise when on guard at RIAT I’ve been “chastised” by (then) VRT officers for not letting them through without ID.
Regulars generally have a dim view of cadets for many reasons. Some warranted, most not.
My biggest complaint I have heard is actually saluting cadet officers. (This obviously comes from rankers).
What stops me now is just exhaustion after a working week, looking at spending extra hours in uniform doesn’t appeal. I want time with my family, not to be (in no way derogatory is this meant) a babysitter.
