Нужно перераспределить рабочую нагрузку, то есть делегировать задачи.

Russian often uses impersonal constructions when the sentence is about necessity, possibility, obligation, and so on.

Here, нужно means something like it is necessary / it is needed. Because of that, Russian does not need an explicit subject like we, you, or someone.

So:

• Нужно перераспределить рабочую нагрузку = It is necessary to redistribute the workload

The person who should do it is understood from the wider context, not from the sentence itself.

This is very common in Russian:

• Нужно подождать. = It’s necessary to wait.
• Нужно позвонить ему. = It’s necessary to call him.

If you want to make the subject explicit, you can:

• Нам нужно перераспределить рабочую нагрузку. = We need to redistribute the workload.
• Вам нужно делегировать задачи. = You need to delegate tasks.

After нужно, Russian normally uses the infinitive.

So the pattern is:

• нужно + infinitive

Examples:

• Нужно сделать это.
• Нужно обсудить проблему.
• Нужно делегировать задачи.

This works much like English need to do something, except Russian uses an impersonal structure:

• Нужно сделать = It is necessary to do / Need to do

So in your sentence:

• нужно перераспределить
• то есть делегировать

both verbs stay in the infinitive because they describe the action that is necessary.

Because нагрузку is the direct object of перераспределить, it must be in the accusative case.

The dictionary form is:

• рабочая нагрузка = workload

But in the accusative singular, feminine nouns ending in -а change:

• нагрузка → нагрузку

And the adjective must agree with the noun:

• рабочая → рабочую

So:

• рабочая нагрузка = nominative
• рабочую нагрузку = accusative

This is a standard feminine pattern:

• новая задача → новую задачу
• важная проблема → важную проблему

The base verb is распределить = to distribute / allocate.

The extra prefix пере- adds the idea of again, differently, or re-.

So:

• распределить = distribute
• перераспределить = redistribute / reallocate

That fits the sentence well: the workload is not being assigned for the first time, but assigned again or in a new way.

You can think of the structure like this:

• распределить = spread out / assign
• перераспределить = reassign / redistribute

This prefix is very common in Russian:

• писать = write

• переписать = rewrite

• делить = divide
• переделить / перераспределить = divide again / redistribute

То есть means that is, that is to say, or in other words.

It introduces an explanation or clarification of what came before.

So here:

• Нужно перераспределить рабочую нагрузку, то есть делегировать задачи.

means that the second part explains the first:

• redistribute the workload
• that is, delegate tasks

In other words, the sentence is saying that one practical way to redistribute the workload is to delegate tasks.

This expression is extremely common in both spoken and written Russian.

Examples:

• Он филолог, то есть специалист по языку и литературе.
• Нужно сократить расходы, то есть тратить меньше.

Because то есть introduces an explanatory phrase, and in Russian that is normally set off with punctuation.

So the comma marks that the second part is explaining or restating the first part:

• Нужно перераспределить рабочую нагрузку, то есть делегировать задачи.

This is similar to English punctuation with that is or in other words.

You will often see commas with expressions like:

• то есть
• а именно
• например
  depending on the structure

So the comma here is not optional in normal writing.

Here задачи is accusative plural, because it is the direct object of делегировать.

The dictionary form is:

• задача = task

Plural nominative:

• задачи = tasks

For inanimate nouns, the accusative plural is usually the same as the nominative plural. So:

• nominative plural: задачи
• accusative plural: задачи

That is why the form does not change.

Compare:

• Я вижу столы.
  столы = accusative plural, same as nominative plural because tables are inanimate

But with animate nouns, accusative plural is different:

• Я вижу студентов.

So in your sentence:

• делегировать задачи = to delegate tasks

Перераспределить is perfective. It presents the action as a complete result: the workload should be redistributed.

Its imperfective partner is:

• перераспределять = to be redistributing / to redistribute in a general or repeated sense

After нужно, both aspects are possible in Russian, but they mean slightly different things:

• Нужно перераспределить нагрузку.
  Focus on achieving the result.
• Нужно перераспределять нагрузку.
  More like a general process or repeated practice.

In your sentence, the perfective makes sense because it points to a concrete necessary outcome.

As for делегировать, this verb is often treated as biaspectual, meaning it can function as imperfective or perfective depending on context. Many borrowed verbs in -ировать behave this way.

So learners may notice that:

• перераспределить has a clearly marked perfective form
• делегировать often does not change form in the same way

That is normal.

Yes. Russian word order is relatively flexible, although not completely free.

The sentence as written is neutral and natural:

• Нужно перераспределить рабочую нагрузку, то есть делегировать задачи.

But other orders are possible for emphasis. For example:

• Рабочую нагрузку нужно перераспределить, то есть делегировать задачи.
  This puts more focus on the workload.

• Нужно делегировать задачи.
  A shorter version focusing directly on the practical action.

Even when the order changes, the case endings tell you what role each word plays, which is why Russian can move words around more easily than English.

A helpful stress-marked version is:

Ну́жно перераспредели́ть рабо́чую нагру́зку, то есть делеги́ровать зада́чи.

A few pronunciation notes:

• нужно = NUZH-no
• перераспределить has stress on -ли́ть
• рабочую has stress on бо́
• нагрузку has stress on гру́
• делегировать has stress on ги́
• задачи has stress on the second syllable: зада́чи

Also, in normal speech, unstressed vowels are reduced, so the sentence may sound less like each vowel is pronounced fully than an English speaker expects. That is completely normal in Russian.

It is natural, but it is not the only option.

Some close alternatives are:

• распределить задачи = distribute the tasks
• передать часть задач коллегам = pass some of the tasks to colleagues
• разделить обязанности = divide responsibilities

The choice depends on nuance:

• делегировать задачи emphasizes assigning tasks to someone else with authority or responsibility
• распределить задачи is broader and can just mean divide the tasks among people
• перераспределить рабочую нагрузку is even broader, because it refers to the workload as a whole, not just individual tasks

So the sentence is natural because the second part explains one specific way to do the first part.
