Hello TamaraL
I was born in 1988, so my Neptune is a bit far from the others. However, these three planets are in the same 6th house in my birth chart also, and the way I see it, they make me a bit rebelious regarding working in offices and having someone bossing me around, especially when I don't have my heart in it.
Maybe the 1989 kids with a stellium in these planets in the 6th house might not be so prone to work in regular jobs, as if they were part of a machine. They must have their hearts on it (Neptune) and feel that no one can give them comands (Uranus).
Anyway, these are just some insights.
