To better understand the plight of low-wage workers, ATTN: spent time with four people who participated in the Fight for 15's rally to raise the minimum wage.

We talked to Bartolomé Perez, a 20-year McDonald's veteran who has only seen his pay increase by $6.50 an hour over more than two decades.

Here's Albina Ardon, who is trying to raise a family on less than $10 an hour.

We also met Samuel Homer-Williams, a college student trying to work his way through school on extremely low wages.

Finally, we spoke with Mary Kay Henry of SEIU, who read and answered comments on the ATTN: Facebook page that were critical of the Fight For 15's actions against McDonald's.

Take action now.
