직원 means employee or staff member.

The -이 is the subject particle. It marks 직원 as the doer of the action.

So:

• 직원 = employee
• 직원이 = the employee / an employee (as the subject)

In this sentence, 직원이 tells you that the employee is the one who performed the collecting.

-를 is the object particle. It marks the thing that receives the action.

So:

• 마대 = sack, bag, burlap sack, collection bag
• 마대를 = the sack/bag (as the object)

In this sentence, the employee is doing the action to the 마대, so -를 is used.

마대 usually refers to a large sack, often a burlap sack or heavy-duty collection bag used in work, storage, trash collection, recycling, construction, and similar contexts.

It is not usually the first word beginners learn for bag. More common general words are:

• 가방 = bag
• 봉지 = plastic bag / small bag
• 자루 = sack, bagful, or counting word for sacks

마대 sounds more specific and practical, often used in workplace or industrial contexts.

수거했습니다 comes from the verb 수거하다, which means to collect, to pick up, or to gather for removal.

It breaks down like this:

• 수거하다 = to collect
• 수거했- = collected / did collect
• -습니다 = formal polite sentence ending

So 수거했습니다 means:

• collected
• has collected
• did collect

depending on the English context.

Both are correct, but they are different speech levels.

• 수거했습니다 = formal polite
• 수거했어요 = polite but less formal

The -습니다 style is common in:

• announcements
• reports
• business contexts
• official writing
• formal conversation

Since this sentence sounds like something from a workplace, notice, or report, 수거했습니다 fits very naturally.

Korean usually does not mark articles like the or an, and it often does not mark plural unless needed.

So 직원이 could mean:

• the employee
• an employee
• sometimes even a staff member

The exact English translation depends on context.

If Korean wants to clearly show plural, it can use 직원들이 for employees, but plural marking is often omitted when context already makes it clear.

The basic Korean order here is:

• 직원이 = subject
• 마대를 = object
• 수거했습니다 = verb

So the sentence follows the common Korean pattern:

Subject + Object + Verb

That said, Korean word order is more flexible than English because particles show each word’s role.

For example, these can still be understood:

• 마대를 직원이 수거했습니다.
• 직원이 수거했습니다, 마대를. (more marked, context-dependent)

But the most neutral and natural form is the original:

직원이 마대를 수거했습니다.

Yes. Korean often omits words that are obvious from context.

For example:

• 마대를 수거했습니다. = (Someone) collected the sack(s).
• 직원이 수거했습니다. = The employee collected it/them.
• 수거했습니다. = (It/they/someone) collected / has been collected / did collect, depending on context

In a full standalone sentence for learners, Korean often includes both subject and object to make the structure clear.

A natural pronunciation is approximately:

• 직원이 → 지그원이 or more closely 지궈니
• 마대를 → 마대를
• 수거했습니다 → close to 수거해씀니다

A few pronunciation notes:

• In 직원이, the final ㄱ in 직 links into the following vowel, so it does not sound like a hard stop.
• In 했습니다, the ㅆ and following sounds make it sound like 해씀니다 in actual speech.

A rough full pronunciation is:

지궈니 마대를 수거해씀니다

They are similar, but not identical.

• 수거하다 = to collect, pick up, gather for removal
  
  • often used for trash, recycling, documents, laundry, items to be taken away
• 모으다 = to gather, collect together
  
  • focuses on bringing things together
• 가져가다 = to take away
  
  • focuses on carrying something away from a place
• 회수하다 = to retrieve, recall
  
  • often used in formal or technical contexts, such as defective products

So 수거하다 is a good choice when something is being collected from a location, especially in a practical or workplace setting.

Yes. In this sentence, 수거했습니다 presents the action as a completed past event.

So it means the collecting was done.

Depending on context, English may translate it as:

• collected
• has collected
• picked up

Korean past tense does not match English tense one-to-one, so the best English version depends on the situation.

Korean does not normally use articles like English the and a/an.

So:

• 직원 can mean employee, an employee, or the employee
• 마대 can mean a sack, the sack, or sacks, depending on context

When translating into English, you add the or a based on what makes sense in the situation.

That is very normal in Korean, and learners should get used to relying on context rather than expecting articles to appear.
