A job at Barneys New York once represented a glimmering opportunity in a challenging retail landscape — the kind of chain where sales associates might work for decades, earning competitive salaries as well as commissions, while honing expertise in fine jewelry and designer apparel.

But that reality evaporated soon after Barneys filed for bankruptcy last year and liquidation specialists took over its stores. Since November, employees at Barneys’s flagship at Madison Avenue and 61st Street have been in limbo, lacking basic information about the store’s closing date, severance pay and their benefits.

Paychecks were delayed this month after what a company email said was a “cyber incident,” further stressing employees, who don’t know if their personal information was compromised.

Many of the concerns were detailed in a letter filed on Tuesday to the judge overseeing the bankruptcy case from employees who have worked at Barneys for more than 20 years.
