Businesses need waivers to keep physical workplaces open if they’re not among the industries the administration defined as life-sustaining. The state Department of Community and Economic Development has declined to disclose the names of the more than 42,000 waiver applicants, though spokeswoman Casey Smith said it will at some point after the department has finished reviewing applications. As of Thursday, the administration had reviewed all but about 1,000 applications — approving about 8,000, denying about 19,000 and dismissing more than 14,000 that were filed unnecessarily by businesses that didn’t need an exemption.
