MILAN — A month after resolving winding-up petitions filed by a pool of U.K.-based creditors, luxury lingerie brand La Perla has allegedly didn’t pay its Italian staffers this month, based on a note issued by local trade unions.

The Filctem-Cgil and Uiltec-Uil unions said in a joint statement that the corporate, now owned by German businessman Lars Windhorst’s private equity firm Tennor, and based in London, didn’t pay wages to its Bologna, Italy-based employees this month. They unpaid employees reportedly total 350.

“We consider this as an act of utmost seriousness which confirms the caliber of the management’s commitment to the La Perla Group,” the unions said. “In consideration of this umpteenth act of disdain from La Perla’s management team we urge [parties] to collect at a round table on the ministry [of Enterprises and Made in Italy],” they added.

Unions claim the ministry has yet to summon the parties to search out a way forward for the corporate’s operations in Italy although the Emilia-Romagna region and the town of Bologna have each urged it to accomplish that.

La Perla representatives didn’t immediately reply to requests for comment Thursday.

Within the U.K. the brand had been served winding-up notices in past months by Purple PR; the accountancy firm Mazars; the design agency Edge Retail, and the consultancy firm HSO Enterprise Solutions. Petitions have since been withdrawn after La Perla paid its debts, as reported last month, apart from the latter, as the corporate still owes HSO Enterprise Solutions greater than 701,129 kilos, and a winding-up petition was still pending last month.

The troubled innerwear brand has been searching for brand new revenue streams and has expanded into beauty and swimwear. It became certainly one of the primary brands to affix Amazon Luxury Stores. The corporate also invested $50 million into the now-shuttered British couture house Ralph & Russo.
