Decisão extraída
The placement in salary grade 5 was not unconstitutional or otherwise unlawful.
Fundamentação extraída
The cantonal method for comparing reference salaries was not arbitrary; the challenged reference values and the choice of calculation variant A were permissible, and even the appellant's corrected figures would not move the result to grade 6.
