On reflection I think MingMong may be right. My office is on a very small station and as such communication isn't as lacking as it is at some stations. I am on the mailing list for all the usual literature, RAF news, Quest, pathfinder, active etc and when things are a bit slow I filter my way through them. All these publications carry adverts for the various service charities, but are obviously only circulated 'in house'. I also get soldier magazine for some reason (?) and this also carries adverts for RAF and RN charities.
SRO's at a small unit are very boring to say the least, we still have paper copies because we are not connected to the intranet. maybe my SRO's aren't the norm as they carry a listing for the local RAFA.
There are definetly messages on the bottom of pay chits, however I quite agree that very few people check anything more than the balance due! I am the same.
However now that I have had time to think I dont remember the last time I saw anything whilst out at other stations. There are adverts in the national press for RAFBF, that much I am sure of, however I have never seen any national advertising for SSAFA, and the legion usually only 'appears' around remembrance day. St Dunstans does have a year round campaign via leaflet drops and the national press.
On balance none of this campaigning is very high profile, and so it's easy to see why it passes people by without much notice.
At this time of the year the RAFA launches it's wings appeal, lets hope they get a good response this year.
