Unite Here Local 1 plans to host a celebration at 9 a.m. Tuesday marking the passage last month of what they refer to as the “Hands Off Pants On” ordinance.

The ordinance requires all hotels in Chicago equip employees with panic buttons if they work alone in guest rooms or bathrooms, starting July 1.

The hotels must also develop sexual harassment policies; they are banned from retaliating against whistleblowers.

Lyons says the union began working on the measure after a survey of some of their 15,000 members who work in hospitality last year found what she calls “shocking results.”
