Struggling online retailer Wayfair on Friday said it will slash around 1,650 employees — or 13% of its global workforce of roughly 14,000 — just weeks after its billionaire CEO caused a stir by saying workers should log longer hours. Niraj Shah, the boss of the Boston-based furniture-selling e-commerce site, said the company needed to cut costs — its third round of layoffs since summer of 2022 –after going “overboard” on hiring during the pandemic.
