Staffing by time band, not by average
We calculate how many people you need each hour from real demand, instead of repeating the usual shift.

Simple estimate: assumes you must cover the same hours and each new worker costs the same. It ignores overtime, time bands and rotating shifts, which is exactly where optimization finds slack.

Frequently asked questions
When does the work week drop to 40 hours?
Law 21.561 reduces it in three steps: to 44 hours on April 26, 2024, to 42 hours on April 26, 2026 and to 40 hours on April 26, 2028.
Do I have to hire more people to comply?
Not necessarily. When coverage relies on fixed shifts, hours are often poorly distributed. Optimizing staffing by time band and the shift roster shrinks the gap before hiring.
How accurate is this calculator?
It is an order-of-magnitude estimate: it assumes the same hours to cover at the same cost per worker. An assessment with your real data gives the gap by shift and time band.
