Férias remuneradas e décimo terceiro são benefícios trabalhistas.

In Brazilian Portuguese, férias is normally used as a plural noun when it means vacation time from work or school.

So you say:

• Estou de férias. = I’m on vacation.
• Minhas férias foram ótimas. = My vacation was great.

Even though it is plural in form, it often corresponds to singular vacation in English. This is just a difference between the two languages.

Remuneradas agrees with férias.

Since férias is:

• feminine
• plural

the adjective also has to be:

• feminine
• plural

So:

• férias remuneradas = paid vacation

Compare:

• salário remunerado would be masculine singular
• horas remuneradas would be feminine plural

This is a basic agreement rule in Portuguese: adjectives usually match the noun in gender and number.

In Brazil, décimo terceiro refers to the 13th salary or year-end bonus that employees usually receive.

Literally, décimo terceiro means thirteenth. In this expression, the full idea is something like décimo terceiro salário. Very often, salário is omitted because the phrase is so common.

So:

• décimo terceiro salário = thirteenth salary
• décimo terceiro = the same thing, shortened

Portuguese often omits articles in general statements, especially when talking about categories or concepts.

So:

• Férias remuneradas e décimo terceiro são benefícios trabalhistas.

means Paid vacation and the 13th salary are labor benefits in a general sense.

You could sometimes hear or read:

• As férias remuneradas e o décimo terceiro são benefícios trabalhistas

but this sounds more definite or more formal, depending on context. The version without articles is very natural in explanatory or informational language.

The subject is made of two things joined by e:

• férias remuneradas
• décimo terceiro

Because the subject is plural overall, the verb must also be plural:

• são = are

If there were only one subject, you would use é:

• O décimo terceiro é um benefício trabalhista.

Trabalhistas means something like labor-related, employment-related, or related to workers’ legal rights.

In benefícios trabalhistas, it refers to benefits connected to labor law or employment rights.

It comes from trabalho = work, but trabalhista is not just work in a general sense. It usually has a legal or labor-rights flavor.

For example:

• direitos trabalhistas = labor rights
• legislação trabalhista = labor legislation
• benefícios trabalhistas = employment/labor benefits

You might be understood, but benefícios trabalhistas is the more natural and standard expression in Brazilian Portuguese.

Benefícios de trabalho sounds less idiomatic and more vague. It could sound like benefits related to work in a broad sense, while benefícios trabalhistas clearly points to worker benefits recognized in the employment/labor context.

So if you want natural Brazilian Portuguese, benefícios trabalhistas is the better choice.

Yes. It is masculine because the hidden noun is salário, which is masculine:

• o salário
• o décimo terceiro salário
• shortened: o décimo terceiro

That is why you would say:

• O décimo terceiro é obrigatório em muitos casos.

not:

• A décima terceira, unless you were referring to a feminine noun in a different context.

Because e simply connects the two parts of the subject:

• férias remuneradas
• décimo terceiro

In Portuguese, just like in English, you normally do not use a comma before e when joining two items in a simple list or compound subject.

So:

• Férias remuneradas e décimo terceiro são... is correct.

Yes, but some versions sound more natural than others.

The original:

• Férias remuneradas e décimo terceiro são benefícios trabalhistas.

is clear and natural.

You could also say:

• Décimo terceiro e férias remuneradas são benefícios trabalhistas.

This is also correct.

You could even say:

• Benefícios trabalhistas incluem férias remuneradas e décimo terceiro.

That changes the structure but keeps the same general idea.

A helpful approximate pronunciation is:

• décimo ≈ DEH-see-moo
• terceiro ≈ tehr-SAY-roo

A few useful notes:

• The accent mark in décimo shows the stressed syllable: DÉ
• In Brazilian Portuguese, ei in terceiro often sounds like ay
• Final o often sounds like a light oo in many Brazilian accents

So the whole phrase sounds approximately like:

• DEH-see-moo tehr-SAY-roo

Yes, very much so. Férias remuneradas is a common and standard expression for paid vacation or paid leave.

You will often see it in contexts about employment rights, contracts, HR, and labor law.

Related expressions include:

• tirar férias = to take vacation
• estar de férias = to be on vacation
• férias vencidas = accrued/overdue vacation time
• férias coletivas = collective vacation period

So this is a useful chunk to learn as a set phrase.

It sounds neutral to slightly formal. It would fit well in:

• an explanation about worker rights
• an HR document
• a textbook
• an informational article

It is not overly technical, but benefícios trabalhistas gives it a somewhat institutional or legal tone.

In very casual speech, someone might phrase the idea more loosely, but this sentence is perfectly natural and standard Brazilian Portuguese.
