Walmart is adjusting operating hours starting Sunday due to coronavirus.

Neighborhood Markets and Walmart stores will be open from 6 a.m. to 11 p.m. until further notice, according to a blog post from Walmart Executive Vice President Dacona Smith.

"This will help ensure associates are able to stock the products our customers are looking for and to perform cleaning and sanitizing," Dacona stated.

Stores that are already operating under more reduced hours — for example, they close at 10 p.m. or open at 7 a.m. — will continue with those hours.

"As we make this change, associates will continue to work the hours and shifts they are scheduled, and our supply chain and trucking fleet will continue to move products and deliver to stores on their regular schedules," Dacona wrote.

Walmart has a temporary COVID-19 emergency leave policy.

According to a corporate blog post, should an employee feel uncomfortable going to work due to coronavirus concerns, Walmart will waive its attendance occurrence policy through the end of April, but employees should still call to let them know. Paid time off options are also available.

If a store, club, office or distribution center is part of a mandated quarantine or if an employee is required to quarantine by a government agency, they will receive up to two weeks of pay, and absences during this time that will not count against attendance.

If an associate has a confirmed case of COVID-19, they will receive up to two weeks of pay. If they're not able to work after that time, additional pay replacement may be given up to 26 weeks for both full-time and part-time hourly associates.

A store associate in Cynthiana, Kentucky, tested positive for COVID-19, according to a Walmart corporate blog post.

"The associate is receiving medical care, and her condition is improving," the post stated. "We wish her a speedy recovery. After learning of this case, we consulted with state and local health experts, reinforced our cleaning and sanitizing protocol, and, with the support and encouragement of the state government, the store remains open."
