What this means in practice
Wage preservation turns transition advice into arithmetic: a pathway with a preservation score of 90 suggests the target role's typical wage is about 90% of the current role's. Scores above 100 indicate an upgrade — the target pays more than the origin.
The score protects against a common trap in career advice: recommending safe moves that quietly cut pay. A Receptionist moving into office coordination preserves most of their wage, while some adjacent service roles would preserve far less — a difference the number makes visible before a worker commits to retraining.
