Chicago hotels are now rolling out “panic buttons” for hotel staff to address the threat of workers being “sexually assaulted or harassed by guests,” according to The Chicago Tribune. An ordinance approving the buttons was passed in October, and now the city is pushing to get the devices distributed by a July 1 deadline.

When pressed, the buttons would send a message that “instantaneously goes to the cellphones of supervisors” that would include the “device number, the name of the employee in distress, and room number where she is located.”
