13.3.1 Prefer singular agreement for collective nouns
When using "management," "company," "staff,"
or other such collective nouns, use singular verb agreement.
That is the U.S. convention. Furthermore, if these are in singular
agreement, any pronouns referring to them should be singular,
as in "The company treats its employees well," not
"their employees."
