Is the author of this using the same pc as the 'Real Soldiers' write up ?
All siggies are low band, regardless of trade , you only get your high band when you get your first banana.
When you hit ssgt you drop to low band again. Staffies run a troop , with a lot of expensive kit in it , a bit more responsibility than a line store or whatever and they get on with it. They got graded without someone there to fight the corner of Royal Signals Ssgts (someone correct me if I'm wrong) and got put in the same financial grading as an infantry CSgt who ends up normally just running a CQMS or something.
The only Sigs SSgts on high band are those in supervisor roles.
If you're so unhappy that the 'less technical operators' are on high band, answers easy , retrade.... either that or vote with your feet about your displeasure and get out find a job in fleet management or something, they pay starting 25-30k plus if you look on Monster jobs
Personally I don't give a monkeys , I'm off to roll around on my pile of over inflated operator pay slips , I'm scared to drop my purse , or as BBJP used to say it would be 'Surfs up in Japan'
