KEY WEST, Fla. (AP) — U.S. Postal Service workers and American Postal Workers Local 620 union members are protesting staffing shortages resulting in mail delays and an overextended workforce.

The Key West Citizen reports Monday’s protesters collected signatures near two different USPS offices in Key West while waving signs reading “Cutting Service Is Not The Answer” and “Keep High Delivery Standards,” among other phrases.

The newspaper reports protesters say the harm caused by lowering service standards in 2015 and closing 80 distribution centers needs to be addressed by the U.S. Postmaster General and the USPS Board of Governors. Union President Omayra Cruz says offices across the country are increasingly short staffed, causing long lines, late nights, unsent mail and unopened offices.

Cruz says the union isn’t planning a strike.
