Nearly all Local Councils and Government agencies refer to pay rate structures as Bands and then each band will have specific levels or steps. Employees proceed up the banding after performance reviews etc.
Each specific Banding refers to a group or job activities, requirements, qualifications etc required to do the work
There are many terms for this such as levels, bands, grades, steps etc.
What I tried to explain above is much better understood if you have a look at a previous EBA or Award.
