Why this is a win for Other Service Industry Workers

I want to analyze this proposal from the perspective of Other Service Industry Workers. There's a civic proposal to convert the WSCC Arch building at 7th & Pike into a year-round public commons operated by Seattle Center. The case being made to Other Service Industry Workers: The service economy of the Pike/Pine corridor depends on foot traffic. A commons that brings year-round activation to the Arch building creates jobs across the service economy — retail, hospitality, events, maintenance, and security. The workers who would benefit most are the ones currently bearing the cost of a dark building: fewer shifts, thinner margins, less stable work.
