Calculate night shift hours and the premium they attract.
The premium rate is the base rate multiplied by the uplift, and total pay adds it to ordinary hours. Showing the premium as a share of total pay makes clear how much of the wage bill is discretionary. Night Shift consistently above about 15% of the wage bill is usually cheaper to solve with another hire than to keep paying at a premium.
