yàobúshì zhèxiē fúlì, wǒ búhuì xuǎnzé quánzhí gǎngwèi.

要不是 means if it weren’t for... / but for.... It introduces a reason that changed the outcome.

So:

• 要不是这些福利，我不会选择全职岗位。
• If it weren’t for these benefits, I wouldn’t choose a full-time position.

It usually implies a counterfactual idea: the speaker did choose the full-time position, and the benefits were the key reason.

It is very close to 如果不是, but 要不是 often sounds a bit more natural and idiomatic in everyday speech for this kind of “but for” meaning.

Yes. That is the usual implication.

The structure:

• 要不是 X，Y 不会...

strongly suggests:

• Because of X, Y did happen.

So here, the sentence implies:

• The speaker did choose a full-time position.
• They chose it because of these benefits.

In English, this is like saying:

• If it weren’t for these benefits, I wouldn’t have chosen a full-time position.

Even though the Chinese says 不会选择, the overall meaning is typically about a real choice that was made.

Great question. The difference is about type of negation.

• 不会选择 = would not choose / would not be willing to choose
• 没选择 = didn’t choose

In this sentence, the speaker is talking about a hypothetical result:

• If it weren’t for these benefits, I would not choose...

That is why 不会 fits better than 没.

If you said:

• 要不是这些福利，我没选择全职岗位

that would sound odd, because 没选择 describes a past fact, not the hypothetical/counterfactual idea that this pattern needs.

This is due to tone sandhi.

Normally:

• 不 is fourth tone: bù

But when 不 comes before another fourth-tone syllable, it changes in pronunciation to second tone:

• 不
  • 会 (huì, 4th tone) → pronounced bú huì

Important:

• The character is still written 不
• Only the pronunciation changes

So:

• Written: 不会
• Pronounced: búhuì

这些 means these.

It is made of:

• 这 = this
• 些 = some / a plural group

Together, 这些 means these.

A measure word is not needed here because 些 already functions as a kind of plural marker.

Compare:

• 这本书 = this book
• 这些书 = these books

So in your sentence:

• 这些福利 = these benefits

Here, 福利 means employee benefits or job benefits.

Common examples include:

• health insurance
• paid leave
• bonuses
• housing allowance
• retirement contributions

A learner may know 福利 as welfare, and that meaning does exist in some contexts, but in workplace Chinese it very often means benefits/perks.

So in this sentence, 这些福利 is best understood as:

• these job benefits
• these employment benefits

Both can refer to a job, but they are not exactly the same.

• 工作 = work / job
• 岗位 = position / post / role

岗位 sounds a bit more formal and specific, especially in hiring, HR, or workplace contexts.

So:

• 全职工作 = full-time job
• 全职岗位 = full-time position

Both are possible, but 全职岗位 sounds a little more like something you might see in recruitment language.

Yes, absolutely.

These are both natural:

• 选择全职岗位
• 选择全职工作

The difference is mainly in tone:

• 全职工作 sounds more everyday and general
• 全职岗位 sounds a bit more formal or professional

So if you are speaking casually, 全职工作 may feel more natural.
If you are talking about employment options, HR, or a formal decision, 全职岗位 works very well.

Chinese often puts the condition or reason first, then the main result.

So the structure is:

• 要不是 + reason, + result

Here:

• 要不是这些福利 = if it weren’t for these benefits
• 我不会选择全职岗位 = I wouldn’t choose a full-time position

This order is very natural in Chinese.

You can think of it as:

1. Set up the condition
2. State the consequence

It can be added, but it is not required.

You may hear:

• 要不是这些福利，我就不会选择全职岗位。

The 就 helps emphasize the result, something like:

• then / in that case / as a result

Without 就, the sentence is still completely natural:

• 要不是这些福利，我不会选择全职岗位。

So:

• with 就 = slightly more explicit/emphatic
• without 就 = still correct and common

No, they are different.

• 因为 = because
• 要不是 = if it weren’t for / but for

Compare:

• 因为这些福利，我选择了全职岗位。 = Because of these benefits, I chose a full-time position.

• 要不是这些福利，我不会选择全职岗位。 = If it weren’t for these benefits, I wouldn’t choose a full-time position.

The second one is more emphatic and more clearly shows that the benefits were the deciding factor.

Not really in this sentence.

Although 要 often means want, in 要不是 you should learn it as a fixed expression.

So don’t analyze it as:

• 要 = want
• 不是 = is not

Instead, treat 要不是 as one chunk meaning:

• if it weren’t for
• but for

This is much easier and closer to how native speakers understand it in context.

It is fairly neutral, with a slight formal/professional feel because of words like:

• 福利
• 全职
• 岗位

The grammar 要不是...我不会... is common in spoken and written Chinese, but the vocabulary makes the sentence sound like something related to employment decisions.

A more casual version might be:

• 要不是这些福利，我才不会选全职工作。

That sounds more conversational and stronger in tone.

Your original sentence is natural and appropriate, especially in workplace or interview-related contexts.
