The Pierre hotel has suspended a supervisor and agreed to equip all room attendants with panic buttons in the wake of two alleged sexual attacks on Manhattan hotel housekeepers in about as many weeks.

The decision came after meetings with union officials, who pressed for strengthened protection for workers.

"Let everybody in the world traveling to New York know that when they stay in a hotel room, the person cleaning that room is armed with a button that they can immediately press if you're stupid enough to get inappropriate," said Peter Ward, president of the New York Hotel & Motel Trades Council, which represents about 30,000 workers.

A Pierre spokeswoman, Nora Walsh, confirmed that the hotel will give room attendants the alarms—modeled after those used by some elderly people to alert a central security office—as soon as a system can be devised.

The Sofitel New York—where former International Monetary Fund chief Dominique Strauss-Kahn was accused of an assault—has also agreed to arm attendants with panic buttons, union officials said. Sofitel officials did not respond to requests for comment.
