alt Hacker NewsNot according to my references:
"When to use a singular verb
- When all the members of a collective noun are performing an action as a unit (and that’s usually the case), use a singular verb.
- The chamber orchestra often plays at the Art Centre.
When to use a plural verb
When the members of a collective noun are performing an action as individuals, use a plural verb. In this case, all or some members of the group are doing something independently of the other members; the group is not acting together as a unit.
- The orchestra are tuning their instruments.
- The cast have been practising their lines."

That applies to NA English. And even there, as the reference says, notional agreement (verb/pronouns in plural) can be used when it’s more about the individual members of the collective doing something. So GP’s rule that only grammatical agreement (verb/pronouns in singular) is ever correct is wrong even in NA. But in BrE notional agreement is the most idiomatic choice while grammatical agreement is certainly also fine, just not standard style.
