Can I use this online tool for union differential rules?

The 2026 update uses simple planning differentials. If your contract uses different premiums, treat this as a starting estimator and adjust the narrative with your CBA rates.

Can nurse or retail teams use different weekend premiums?

The default is +25% weekend and +35% night. If your CBA uses other rates, treat the delta as a starting score and reweight with your contract percentages.

How it's calculated

How it's calculated: Weighted hours = hours × (1 + 0.25×weekend + 0.35×night). Person A = 8.0h → 10.00; Person B = 8.0h → 10.80. Delta (A − B) = -0.80. Verdict: Person A owes Person B (approx $17.60 at $22/hr).

Formula summary: weight(h, weekend, night) = h × (1 + 0.25×weekend + 0.35×night) ; delta = weight_A_gives − weight_B_gives

Score whether a shift swap is equitable

Each person gives hours weighted for weekend (+25%) and night (+35%). The delta says who owes whom. Use it for nurse, retail, or warehouse swaps before the schedule locks.
