Workers at an Apple store in Baltimore, Maryland are taking steps to unionize. The organizers alerted CEO Tim Cook of their plans to file for an election with the NLRB. The workers have been coordinating with the International Association of Machinists and Aerospace Workers and will organize as AppleCore. They have signatures from over 65% of employees who should be eligible to vote in the election.
