This kind of Serbian future tense is used only in subordinate clauses (dependent sentences) and never on their own. Ja ću raditi – I will do is a proper future tense that shows an action that will happen in the future, and there is another form of the future tense in which this sentence would look like Ja budem radio. Formally, this tense is called „Future II“. Some linguists say that this is a tense, and some say that it is a mood. As it was said before, this form of Serbian future tense can be used only in the subordinate clause, and to be more specific, only with these conjunctions:

Ako – if

Kad – when

Dok – while, until

Čim – as soon as

One can draw a parallel with the subjunctive mood in Spanish or in English here.
