Toys R Us isn’t paying severance to its 30,000 workers who will lose their jobs as the retailer shuts down, even though it doled out millions in executive bonuses a week before it filed for bankruptcy. Now, some workers are calling on lawmakers to create new rules that would require bankrupt companies backed by private-equity firms to provide compensation to their workers. On Friday, more than a dozen workers met with lawmakers in New Jersey, where Toys R Us is based, to push for severance pay.
