kensyuu to itte mo, zissai ni gyoumu wo simasu.

The key readings are:

研修 = けんしゅう
実際 = じっさい
業務 = ぎょうむ
言っても / いっても = いっても

So the whole sentence is read:

けんしゅう と いっても、じっさい に ぎょうむ を します。

Also, in normal Japanese writing, it would usually be written without spaces: 研修といっても、実際に業務をします。

Here, といっても means something like even though it's called..., although we say..., or even if it is considered....

So 研修といっても gives the idea:

Even though it's called training...

It sets up a contrast between the label and the reality: it is called training, but in reality people are doing actual work.

That is a very common question.

In this pattern, a noun can go directly before といっても, so 研修といっても is natural and standard. You can think of 研修 as the label being quoted: training, though...

Learners often expect something like 研修だといっても, but here the shorter 研修といっても is the normal idiomatic form.

実際に means actually, in reality, or in practice.

It emphasizes that what follows is the real situation, not just the name or appearance. So the sentence contrasts:

研修 = what it is called
実際に = what really happens

That is why it fits very naturally after といっても.

実際 is basically a noun (and can also behave like a na-adjective), and に turns it into an adverb-like expression.

So:

実際 = reality / actual situation
実際に = actually / in practice

This is similar to other words that become adverbial with に.

業務 is a more formal, business-like word. It means something like duties, work tasks, or business operations.

Compared with 仕事:

仕事 = everyday word for work / job
業務 = more official or corporate-sounding word for work duties

So in a company or training context, 業務 sounds more professional and formal.

Because 業務 is a noun, and Japanese often uses the pattern:

noun + をする

So 業務をします means do work duties or perform work tasks.

This is grammatical and natural. In business Japanese, you might also hear:

業務を行う = to carry out duties
仕事をする = to do work

But 業務をします is perfectly fine here.

Japanese often leaves out the subject when it is clear from context.

So します could refer to:

the trainees
we
you
employees in general

The exact subject depends on the surrounding situation. This omission is very normal in Japanese.

Yes. It is at least polite, because it uses します instead of plain-form する. It also sounds fairly formal because of the word 業務.

A more casual version would be:

研修といっても、実際に業務をする。

Not usually in natural English.

Its literal origin is related to say/call, but in real translation it often becomes:

although it's called...
even though it's...
that said...
still...

In this sentence, the most natural English idea is:

Even though it's called training, ...

rather than a stiff literal translation like even if you say training.

The nuance is that this is not just classroom training or practice only.

It suggests:

It may be called training, but people are actually doing real job duties.

So the sentence carries a mild expectation vs. reality contrast: the word 研修 might make you imagine study or observation, but the reality is hands-on work.
