The antecedent of a pronoun is basically the noun that a pronoun replaces, AKA the noun that the pronoun refers to. It should be somewhere before the pronoun in the sentence. In the sentence "Strikers will return to work when the union representative has completed their name negotiation," the pronoun is "their." Whose name negotiation is being completed? The strikers.
