There is a distinction in terms:
- Progression (movement within a level e.g. M2->M3).
- Promotion (movement from one level to the next e.g. C -> M).
Progression is automatic, promotion is assessed. Movement happens once a year (or at mid-year in exceptional cases). So in theory, these could happen:
For exceptional performers, promoted in advance of time-at-level restrictions:
- C1 -> C2 -> M1
For those who meet time-at-level restrictions, and demonstrate performance at mgr level:
- C1 -> C2 -> C3 -> M1
For those who aren't quite performing at mgr level when they first meet time-at-level requiremnts:
- C1 -> C2 -> C3 -> C4 -> M1
For those who are unable to perform at mgr level:
- C1 -> C2 -> C3 -> C4 -> counselled out
Not sure what the stats are about people making manager from C2, C3, or C4. Depends on how well the business is doing, how much demand there is, and money to promote people.
