Seattle City of Literature is asking Washington residents to petition Governor Inslee to reclassify booksellers as essential employees. Here's the most important part of their rationale:

I just sent a letter to the governor asking him to classify bookstores as essential businesses during this crisis. This would give bookstores the opportunity—if they feel comfortable doing so—to support their communities with adapted business models, including curbside pick-ups and deliveries, virtual story times, online book groups, and more.

That "if they feel comfortable" is the most important piece. If booksellers can safely make a living right now, they should be able to. But they should also be able to accept unemployment if they'd rather not put themselves or their families at risk. If you agree, sign the petition.
