ATLANTIC CITY, N.J. (AP) — A union representing housekeeping workers at Atlantic City’s casinos says four of the resorts are not complying with a COVID-related requirement that hotel rooms be cleaned daily.

Local 54 of the Unite Here union said Wednesday that state officials need to enforce an order issued in 2020 by New Jersey Gov. Phil Murphy requiring hotel rooms to be cleaned and sanitized daily. It says Caesars, Harrah’s, Tropicana and the Golden Nugget don’t clean each occupied hotel room each day as required by the order.

The Golden Nugget says staff shortages sometimes prevent daily room cleaning but adds any guest who requests it will get it.

Many hotel chains across the country have adopted new room cleaning protocols brought on by the pandemic and staff shortages. Guests at many hotels and motels are given the option of daily housekeeping for the length of their stay, but it is not standard in many circumstances.
