Learn Croatian: Odbit ću taj posao jer neću poslušati direktora. - I will reject that job because I will not listen to the director.

In the affirmative future tense, when the infinitive comes before the auxiliary verb (ću), verbs ending in -ti drop the final i. That is why odbiti becomes odbit ću. However, in the negative future tense, the negative auxiliary (neću) usually comes first. Because the infinitive poslušati comes after the auxiliary, it keeps its full dictionary form.

Why use poslušati here instead of just slušati?

Slušati means to listen as an ongoing action, like listening to the radio. Poslušati is the completed (perfective) version, which often translates to obeying, complying, or taking someone's advice. Here, the speaker means they will not obey the director's specific instruction, rather than simply refusing to hear his voice.

Both taj posao and direktora are direct objects. Why does direktora get an -a ending while posao doesn't change?

They are both masculine nouns in the accusative case, but Croatian treats living things differently than inanimate objects. For inanimate masculine nouns like posao, the accusative form looks exactly like the nominative (dictionary) form. For animate masculine nouns like direktor, the accusative takes the -a ending.
