Pressure Starbucks to pay employees a living wage

When people think of Starbucks baristas, the general consensus is that they work extremely hard. When you go to Starbucks, you know it's pricey. Most drinks are over $5, so why would you tip your barista?
Here's a secret, Starbucks won't pay their employees a living wage. Most baristas work two jobs to make ends meet, and I'm one of them. I rely on tips to get me gas throughout the week. Baristas that live in major metro areas like New York City, Seattle, Chicago, San Francisco, and LA make minimum wage for that city. Living wages for these metro areas can be up to $20 an hour, guaranteeing a 40 hour work week. This, however, doesn't account for everyone's life situation. Some baristas are single parents with no familial assistance, some are disabled and need an hourly job that is flexible for doctors appointments.
Shift supervisors at Starbucks barely make more than a barista, and they're managers. The pay that is given to non-salaried employees is unacceptable, and we need change. Only pressure from the workers and the public will make Starbucks reconsider their low wages.
