The subordinate clauses of time and condition

N ote 1: The Future Simple Tense is not used in adverbial clauses of time and condition after the conjunctions when, while, till, until, before, after, as soon as; if, unless, in case, on condition that, provided, etc. The Present Simple is used instead.

He doesn’t know if they will work on their own or not.
