İhbar süresini tamamlamaksızın işten ayrılmak istemiyorum.

In employment Turkish, ihbar süresi means the notice period — the amount of time you are expected to keep working after giving notice before leaving a job.

• ihbar = notice, notification
• süre = duration, period, length of time
• ihbar süresi = notice period

So this is a very common HR / workplace expression.

Süresini contains two endings:

• süre = period
• süre-si = its period / the period of it
• süre-si-ni = the period as a definite object

Here’s the breakdown:

• -si is a 3rd person possessive ending. In a phrase like ihbar süresi, Turkish literally structures it like the notice’s period.
• -ni is the accusative ending, used because tamamlamak takes a direct object, and that object is definite/specific.

So:

• ihbar süresi = notice period
• ihbar süresini tamamlamak = to complete the notice period

That is why süresini appears in the sentence.

Tamamlamaksızın means without completing.

It comes from:

• tamamlamak = to complete
• -maksızın = without doing

So:

• tamamlamak = to complete
• tamamlamaksızın = without completing

This ending creates a kind of adverbial expression: it tells you how or under what condition something happens.

In this sentence:

• ihbar süresini tamamlamaksızın = without completing the notice period

Yes — tamamlamadan would also be very natural, and in everyday speech it is often more common.

Compare:

• tamamlamaksızın = without completing
  
  • a bit more formal, written, official, or legal in tone
• tamamlamadan = without completing
  
  • very common in everyday Turkish

So this sentence sounds somewhat formal or professional, which fits the workplace context.

İşten ayrılmak means to leave one’s job / to leave work.

Breakdown:

• iş = work, job
• işten = from work / from the job
• ayrılmak = to leave, separate, depart

The verb ayrılmak usually takes the ablative case (-den / -dan / -ten / -tan) for the place, group, or situation someone leaves.

Examples:

• evden ayrılmak = to leave the house
• okuldan ayrılmak = to leave school
• işten ayrılmak = to leave the job

So işten is exactly what Turkish grammar requires with ayrılmak.

Because it depends on istemiyorum = I do not want.

In Turkish, after istemek (to want), the thing wanted is often expressed with an infinitive:

• gitmek istiyorum = I want to go
• kalmak istiyorum = I want to stay
• işten ayrılmak istemiyorum = I do not want to leave my job

So here:

• ayrılmak = to leave
• istemiyorum = I do not want

Together:

• işten ayrılmak istemiyorum = I do not want to leave the job

Because Turkish commonly uses the -iyor form with istemek.

Breakdown:

• iste- = want
• -mi- = negation
• -yor = present continuous / current state marker
• -um = I

So:

• istiyorum = I want
• istemiyorum = I do not want

Even though -iyor often corresponds to English am/is/are doing, with some verbs like istemek, bilmek, sevmek, it can express a present state very naturally.

So istemiyorum is simply the normal way to say I don’t want.

Because the main verb of the whole sentence is istemiyorum: I do not want.

The speaker is not saying:

• I want not to leave

but rather:

• I do not want to leave

That is why the negation is on istemek:

• ayrılmak istemiyorum = I do not want to leave

If you moved the negation to ayrılmak, the nuance would change.

A helpful way to read it is:

• İhbar süresini tamamlamaksızın = without completing the notice period
• işten ayrılmak = to leave the job
• istemiyorum = I do not want

So the full structure is:

[without completing the notice period] + [to leave the job] + [I do not want]

This is very normal Turkish word order: extra information usually comes before the final main verb.

Yes. A literal breakdown is useful for grammar, but a natural English version would usually be something like:

• I don’t want to leave my job without completing the notice period.
• I don’t want to quit without serving my notice period.

In workplace English, serve my notice is often a very natural equivalent of ihbar süresini tamamlamak.

Yes, somewhat.

The main reasons are:

• ihbar süresi is workplace/legal vocabulary
• tamamlamaksızın is more formal than tamamlamadan

So this sounds appropriate in:

• HR communication
• official statements
• workplace discussions
• formal written Turkish

A more everyday version might be:

• İhbar süresini tamamlamadan işten ayrılmak istemiyorum.

That means the same thing, but sounds a little less formal.
