Nurture your current staff cadets - make them want to return. Maybe not an immediate return, and maybe not to your squadron, but long term, it works.
Contact your ex-cadets - they might be at uni, in employment or moved out of the area - however they’ve been through the cadet system and your contact might be enough to trigger some positive reflections - and perhaps enough to volunteer their time. Perhaps not as staff, maybe as CivCom, but every little helps! Organising something like a squadron reunion can help with this - and will bring a lot of good PR as an aside which will also help.
Contact your local station? See if there are any willing Service Instructors willing to give up some time - or any service leavers you might want to get your claws into early on.
Contact your local volunteer bureau. If it’s anything like ours, the only thing they seem to advertise is minibus drivers or accountants (have a look at the Do-it website for your local area and see what the competition is like!) - the opportunities that we offer staff members - as well as cadets - are significant (and much higher than many organisations out there), so you could easily get some quick PR and potential recruits through that route.
We try to avoid parents.
Induction for us is, unfortunately, managed at Wing level. They show up and our squadron and we have to effectively say “thanks for rocking up - we can’t accept you until you have done this evening course - let me take your details and some faceless civil servant will send you an invitation (probably via email, so it’ll end up in your junk mail)”. They attend a “Volunteer Induction Presentation” which gives an even playing field insight into the ACO, what we do and what opportunities we offer cadets - and staff - the different roles available and other such nonsense. Some existing staff members and WSOs are then rolled out to talk to the “VIPs” and give their experiences. Relevant WSOs then do an initial interview with the VIP to make sure they are not on the Feds top 10 wanted list, aren’t a complete muppet, and that they function as communicative human beings. They then say “where do you live - oh, that squadron is under/over staffed (delete as appropriate) have you thought about 123 (Anytown) squadron which is only (insert massive distance here) away - you might like it”.
At the VIP evening they are issued forms and, depending on the calibre of the WSO leading the operation, we’ll either get the forms back in due course, or never hear of them again!
If we hear back from them, then its parading accompanied on Squadron once DBS is signed off, learning local stuff and actually meeting the cadets. Then off to a BASIC course for a weekend of fun and some basic instructions techniques, and if that’s not bored them rigid, then we’ll set them up on Ultifail to which death by powerpoint for Health & Safety, protection information and other nonsense!
Poster is good - but lacks the corporate branding it should probably have.
