Tate Britain has defended its decision to advertise for a “head of coffee”, on wages of almost £40,000 a year.
Union leaders had said the post highlights “the pay discrepancy” between museum professionals and others within the arts sector.
The average annual salary for professional art curators in London is believed to be around £37,300.
The Tate told the BBC: “It’s unfair to compare a head of department with a curatorial role of a different level”.
“All Tate’s departments have a variety of roles with different responsibilities and salaries,” a spokesman said, “including curatorial, and a more accurate comparison would be a curatorial team leader.”
The museum said curatorial team leaders can be paid around £50,000, while assistants may start on £17,524, as guidelines show.
“We value all our staff and strive to pay them appropriately for their work at Tate,” the statement concluded.
