QUINCY, Mass. (AP) — Stop & Shop is acknowledging that it has limited its offerings during a strike affecting 240 supermarkets in New England and is apologizing to customers for the inconvenience.

Stop & Shop President Mark McGowan said in a letter Tuesday that most stores will remain open for 12 hours, seven days a week. However, he says bakery, customer service, deli, and seafood counters will not be operational. There will also be a limited meat selection.

McGowan says Stop & Shop has also closed its gas stations.

Thousands of workers walked off the job April 11 over what they say is an unfair contract offer. The company disputes that.

Also Tuesday, Stop & Shop confirmed there are additional police and security personnel at some stores as a precaution.
