Zaposleni će stupiti na rad.

It can mean either one, depending on context.

• zaposleni can be:
  • singular masculine: the employee
  • plural masculine / mixed-gender: the employees

In this sentence, će is the same for both he/she will and they will, so the form does not resolve the ambiguity.

So:

• Zaposleni će stupiti na rad.
  • The employee will start work.
  • The employees will start work.

You need context to know which one is meant.

It is originally an adjective meaning employed, but here it is being used as a noun: the employed person / employee.

This is very common in Serbian. Adjectives can function as nouns when the noun is understood.

Compare:

• zaposleni radnik = employed worker
• zaposleni = employee / employees

So in this sentence, zaposleni is perfectly natural and means employee or employees, depending on context.

This is the future tense in Serbian, formed with:

• the auxiliary ću / ćeš / će / ćemo / ćete / će
• plus the infinitive

Here:

• će = will
• stupiti = infinitive, to enter / step into / begin in this expression

So:

• će stupiti = will begin / will enter

A key point for English speakers:

• Serbian uses the same form će for both he/she/it will and they will.

That is one reason the sentence can be ambiguous between singular and plural.

Stupiti na rad is a fairly formal expression meaning:

• to start work
• to take up work
• to commence employment
• to report for work

It is not just the everyday verb to work. It refers more specifically to the moment someone begins employment or officially starts working.

So this sentence sounds more formal than a simple everyday sentence like:

• Zaposleni će početi da radi. = The employee will start working.

Because the meaning is slightly different in tone and usage.

• raditi = to work
• početi da radi = to start working
• stupiti na rad = to formally begin work / take up one’s post

Stupiti na rad is especially common in:

• official notices
• HR language
• contracts
• administrative documents

So if you see this sentence in a formal context, that is very normal.

Because stupiti na rad is a fixed expression.

The preposition na here is part of the idiom. You should learn stupiti na rad as a whole phrase.

Literally, it may feel like step onto work, but that is not how you should interpret it word-for-word. The real meaning is simply:

• to begin work
• to enter employment

This is a good example of where Serbian uses a set phrase that does not translate literally into natural English.

Because after na in this expression, rad is in the accusative singular.

• nominative: rad
• accusative: rad

For this noun, nominative and accusative look the same, so the form does not change visibly.

In stupiti na rad, the structure behaves like movement toward a state/activity, which is why na takes the accusative here.

By itself, stupiti is a perfective verb that can mean things like:

• to step
• to enter
• to come into
• to take effect
• to begin in certain expressions

Its exact meaning depends heavily on the phrase:

• stupiti na snagu = to come into force
• stupiti u kontakt = to make contact
• stupiti na rad = to start work

So it is a useful verb, but often best learned through common combinations rather than in isolation.

Yes, stupiti is perfective.

That matters because perfective verbs often express:

• a completed action
• the beginning or entry into a new state
• a single event

In this sentence, that fits well, because starting work is a single event or transition, not an ongoing process.

That is why stupiti na rad sounds natural for will start work.

It sounds formal or administrative.

You are likely to see it in contexts like:

• employment contracts
• HR announcements
• official decisions
• company notices

In everyday conversation, people might say something more like:

• Zaposleni počinje da radi.
• Zaposleni kreće na posao.
• Počeće da radi.

So the sentence is correct and natural, but its register is more official than casual.

Yes, Serbian word order is fairly flexible, but not all versions sound equally neutral.

The most neutral version here is:

• Zaposleni će stupiti na rad.

You may also encounter:

• Zaposleni stupiće na rad.

That is possible, but it sounds more marked, formal, or stylistically different.

For learners, the safest pattern is:

• subject + će + infinitive

So this sentence is a very good standard model.

On its own, zaposleni is not the usual feminine singular form.

If you specifically mean a female employee, you would normally expect:

• zaposlena = the female employee

So:

• Zaposlena će stupiti na rad. = The female employee will start work.

However, zaposleni can refer to:

• a male employee
• employees as a group
• mixed-gender employees

So if you need to make feminine singular explicit, use zaposlena.

Yes. Another common word is:

• zaposlenik / zaposlenica in some varieties
• radnik in some contexts, though that is not always exactly the same

In Serbian, zaposleni is very common, especially in general and administrative usage.

A rough distinction:

• zaposleni = employee / employed person
• radnik = worker, often more specifically a worker/laborer, though it can be broader depending on context

So in many formal contexts, zaposleni is a very natural choice.

Usually it suggests taking up work or starting work officially, often in connection with a new position or the beginning of employment.

But depending on context, it could also refer to reporting for duty or beginning work on a certain date, not necessarily a brand-new career move.

So the exact nuance depends on the surrounding situation:

• a new hire
• an employee beginning on a scheduled date
• someone formally entering active duty

The core idea is: the person officially begins work.

Some more conversational alternatives are:

• Zaposleni će početi da radi.
• Počeće da radi.
• Kreće na posao. (more colloquial, depending on context)

Compared with these, Zaposleni će stupiti na rad sounds more official and institutional.

So it is a useful sentence to recognize, especially in written Serbian.
