Questions & Answers about watashi wa shourai doko de hataraku ka yoku kangaemasu.

What is the function of か in this sentence, and why is it in the middle instead of at the end?

Here か is marking the end of an embedded (indirect) question, not a normal sentence‑final question.

• どこで働くか = “where (I will) work”
• That whole chunk is the thing that is being thought about by 考えます.

So the structure is:

• [question word + plain verb + か] + 考えます
  
  • どこで働くか考えます = I think about where (I will) work.

This is the same pattern as:

• 何を食べるか決めます。 – I will decide what to eat.
• いつ行くか知っています。 – I know when (someone) will go.

If you wanted a direct question, you would put か at the end:

• 将来どこで働きますか。 – Where will you work in the future?

Why is it 働く and not the polite form 働きます inside どこで働くか?

In Japanese, subordinate clauses (clauses before things like か, と, から, and before nouns) almost always use the plain (dictionary) form, regardless of the politeness of the main verb.

Here:

• Subordinate (embedded question) clause: どこで働くか → plain 働く
• Main predicate: 考えます → polite ます form

Using 働きます inside would be ungrammatical:

• ✅ どこで働くか考えます。
• ❌ どこで働きますか考えます。

Other examples:

• 何を買うか決めました。 (not 買いますか)
• どこに住むか知っています。 (not 住みますか)
