Urban Outfitters Inc. has asked salaried workers at the company’s home office to “volunteer” for extra weekend shifts at a new fulfillment center in the town of Gap, PA.

In an email, the company asked for weekend workers to “pick, pack and prepare packages for shipment.” The three brands beneath the URBN URBN, +0.38% umbrella are Anthropologie, Urban Outfitters and Free People.

Volunteers would work six-hour shifts in exchange for lunch and transportation, if required. The email advises participants to wear “sneakers and comfortable clothing” to prepare for this “team building activity.”

The picking, packing and preparing that’s required are jobs that normally pay wages. But this sort of request is a common occurrence in the industry when there’s a new fulfillment center, according to a spokesperson. The company sought help for next weekend, the one after, and October 31.

Hourly-wage workers were excluded from the email, though the company said some of them responded. ”Many hourly employees also offered to pitch in—an offer which we appreciated, but declined in order to ensure full compliance with all applicable labor laws and regulations,” the company said in a statement.

On Wednesday, Urban Outfitters became the fifth retailer to end on-call scheduling for workers in its New York stores, according to a statement by New York Attorney General Eric Schneiderman.

”As part of this agreement, Urban Outfitters has also agreed to provide employees with their schedules at least one week prior to the start of the workweek,” AG Schneiderman said in a statement. “Workers deserve basic protections, including a reliable work schedule that allows them to budget living expenses, arrange for child care needs, and plan their days.”
