After laying off another 50-60 of its employees - close to half its remaining staff -retailer, the online arm of parent Kmart Corp, is left with little more than a skeleton crew running its website.  Those workers who remain are charged with maintaining key financial and technological procedures, and work in an office space that was originally expected to house around 300 people at the company's peak. In addition, a ground-level retail space, which was to have been the site of a store where consumers could shop over the Internet, remains vacant and Kmart is thought to be in the process of looking for alternative accommodation.
