Faço hora extra e confiro as horas extras com recursos humanos.

Because Portuguese often drops subject pronouns when the verb form already makes the subject clear.

• faço = I do / I make
• confiro = I check / I verify

Both are clearly first person singular, so eu is not necessary.

You can say Eu faço hora extra e confiro as horas extras com recursos humanos, but adding eu usually gives a little more emphasis or contrast.

They are in the present indicative.

In a sentence like this, the present tense usually describes:

• a habit
• a routine
• a general fact about the speaker’s work

So it sounds like: this is something I regularly do.

The infinitive is fazer. Its first-person singular present form is irregular:

• eu faço
• você faz
• ele/ela faz

The ç is important. It makes the sound of s before a.

So:

• faço sounds roughly like FAH-soo in Brazilian Portuguese
• without the cedilla, c before a would normally sound like k

This is very common and natural.

• fazer hora extra is a fixed expression meaning to work overtime
• it often appears in the singular, even when the idea is general and not literally just one hour

Then:

• as horas extras refers to the actual overtime hours being checked
• here the phrase is plural because it is talking about those hours more concretely

So the shift from singular to plural is normal.

Yes. Faço horas extras is also correct and natural.

Very roughly:

• faço hora extra = common, idiomatic, general expression
• faço horas extras = also natural, sometimes feels a bit more countable or concrete

Both are used in Brazilian Portuguese.

No. This is a classic false friend.

In this sentence, conferir means things like:

• to check
• to verify
• to review
• to reconcile

So confiro as horas extras means the speaker checks whether the overtime hours are correct.

It does not usually mean English confer in the sense of discuss formally.

The article as means the.

It is used because the sentence refers to specific overtime hours that are understood in the context — probably the speaker’s own recorded overtime hours.

Compare:

• confiro as horas extras = I check the overtime hours
• confiro horas extras = more general, less definite, and less natural in this context

Here, recursos humanos refers to the HR department or the people in HR.

• com recursos humanos = with HR / with human resources
• com os recursos humanos sounds unnatural here, because it sounds like with the human resources in a very literal way

In everyday Brazilian Portuguese, many people would simply say:

• com o RH

That is probably even more common in speech.

Not exactly.

• com recursos humanos / com o RH focuses on checking the hours with HR, meaning in coordination with them
• no RH focuses more on at/in the HR department

So:

• confiro as horas extras com o RH = I check the overtime hours with HR
• confiro as horas extras no RH = I check the overtime hours at HR / in HR

Both can work, but com highlights interaction with the department or staff.

Usually, in normal running text, recursos humanos is often written in lowercase unless it is being treated as an official department name.

So all of these are possible depending on style:

• recursos humanos
• Recursos Humanos
• RH

In everyday workplace language, RH is extremely common.

Yes, it is natural.

A native speaker might also say:

• Faço hora extra e confiro as horas extras com o RH.
• Faço horas extras e confiro isso com o RH.
• Faço hora extra e depois confiro as horas com o RH.

Your original sentence sounds clear and workplace-appropriate. The most likely everyday change would simply be replacing recursos humanos with RH.
