And her technique is surprisingly inelegant. Martha Stewart Living Omnimedia employees have been home all week since Hurricane Sandy flooded the company’s West Chelsea offices, yet on Thursday the company announced that it’s scaling back two of its four magazines and laying off 70 employees. Everyday Food will be turned into a Martha Stewart Living supplement and Whole Living Magazine will suffer the same fate if it can’t be sold. Now staffers are sitting at home, some in the dark, wondering if they still have a job. “They sent a memo saying, ‘Thinking of you all [during] this demanding and difficult week,’ and then they’ll contact employees individually about the layoffs,” a source tells the Post.
