The night shift premium is a right of urban workers who work between 22h and 5h. The CLT (Brazil’s Consolidated Labor Laws) sets a minimum rate of 20% on top of the daytime hourly rate and also provides for a shortened night hour of 52 minutes and 30 seconds.

Who is entitled to the night shift premium, and during what hours

The night shift premium is set out in art. 73 of the CLT. It applies to urban workers who work between 22 hours on one day and 5 hours on the next. For rural workers in crop farming, night hours run from 21h to 5h. In livestock farming, they run from 20h to 4h, under art. 7 of Law 5.889/1973.

For urban workers, the minimum premium is 20% of the daytime hourly rate. Collective bargaining agreements can set higher rates. Depending on the industry, it is common to find categories of workers who receive a premium of 30%, 40% or even 50%.

Many employers fail to pay the night shift premium correctly, especially for mixed shifts that run past 5h in the morning. Under TST (Brazil’s Superior Labor Court) Súmula 60, II, if the employee works the entire night period and the shift is then extended, the premium is also owed for the extended hours.

The shortened night hour: how the calculation works

One distinctive feature of night work is the shortened notional hour. Under art. 73, paragraph 1, of the CLT, each night hour counts as 52 minutes and 30 seconds. In other words, for every 7 hours worked during the night period (from 22h to 5h), the employee is credited with 8 hours of work for pay purposes.

In practice, this means a night worker is paid for 8 hours even though he or she actually worked 7. When a night shift goes beyond 7 actual hours (at 52 minutes and 30 seconds per notional hour), the excess hours count as night overtime, with the corresponding premium.

For urban workers, the minimum premium is 20% of the daytime hourly rate.

To calculate the night shift premium correctly, you must take into account both the 20% rate on the daytime hour and the shortened hour. When an employer overlooks either of these components, the worker is often owed back pay.

How the night shift premium affects other employment benefits

When the night shift premium is paid on a regular basis, it is considered part of the worker’s salary and is included in his or her pay for all purposes. This means it carries over into vacation pay plus the one-third vacation bonus, the 13th salary, the FGTS (Brazil’s Severance Indemnity Fund), notice pay and other employment entitlements, under TST Súmula 60.

If the employee is transferred to a daytime schedule, he or she loses the night shift premium. TST Súmula 265 provides that the transfer does not create a vested right to keep receiving the premium. However, if the employee worked nights for years and the premium had already become part of his or her regular pay, the issue can be litigated in court.

To recover unpaid or underpaid night shift premium, the worker may file a labor claim within two years after the employment contract ends and can claim the differences owed for the last five years.

The night shift premium under special work schedules

In certain occupations, such as security guards, healthcare workers and drivers, night work may be subject to specific rules set by special legislation or by collective agreements. The 12×36 schedule, for example, may provide for a different way of paying the night shift premium, as long as the legal minimum is respected.

It is worth noting that the Labor Reform (Law 13.467/2017) left the night shift premium provisions fully intact: neither the rates nor the shortened notional hour were changed. Collective bargaining can make many rights more flexible, but the night shift premium remains a minimum floor that cannot be waived. Rural night workers, for their part, receive a premium of 25% of the daytime hourly rate, which is higher than the rate for urban workers.

How to check whether your night shift premium is being paid correctly

The first step in checking whether your night shift premium is being paid correctly is to read your pay stub carefully. It should show, as separate items, the number of night hours you worked in the month, the night hourly rate with the 20% increase, and the corresponding total. If these items are not broken out, that may be a sign your employer is not meeting its legal obligation.

Another key step is to review your time records. Whether your employer uses a time card, an electronic time clock or a digital timekeeping system, the records must accurately show when you clocked in and out. If you work a mixed shift (partly day and partly night), you need to check whether the hours worked after 22h are being paid with the premium and counted using the notional hour of 52 minutes and 30 seconds. Employers that use pre-filled, fixed schedules with no variation may be keeping irregular time records, which is a form of labor fraud that can lead to a court judgment against them.

In labor lawsuits seeking unpaid night shift premium, the most important evidence includes pay stubs, time records, the collective agreement that covers the worker’s category, and any witnesses who can confirm the hours actually worked. When an employer with more than 20 employees fails to produce its attendance records, the hours the worker claims to have worked are presumed to be true unless proven otherwise, under TST Súmula 338, I. As a result, missing records tend to work in the employee’s favor when it comes to proof.

Frequently Asked Questions

Is the night shift premium owed for hours worked after 5h in the morning?

Yes. TST Súmula 60, II, provides that when the worker completes the entire night shift and it is extended past 5h, the premium also applies to the extended hours. The goal is to protect workers who keep working after the legal night period ends.

How is the shortened night hour calculated in practice?

The notional night hour is 52 minutes and 30 seconds. So 7 actual hours (from 22h to 5h) equal 8 hours of work for pay purposes. To calculate, divide the monthly salary by 220 (the standard workload) to find the daytime hourly rate, then apply the 20% premium, taking the shortened notional hour into account.

Does switching to the day shift end the right to the night shift premium?

Yes. TST Súmula 265 allows the employer to move an employee from the night shift to the day shift and stop paying the premium, without this being considered a harmful change to the employment contract. The prevailing view is that there is no vested right to keep the premium once the condition that gave rise to it no longer exists.
