a "model" employee

Maria Fernandes worked three jobs... and she still couldn't get ahead. She could barely stay where she was. Part-timers may, if they shuttle between those part-time jobs, work enough hours to be "full time", but they don't get the wages or the benefits.

This isn't right.

Money quote from the article:

She had an apartment, but was falling behind on the $550 rent despite those three jobs. Dunkin' Donuts said she was a "model" employee, but wouldn't say how much she was paid or how many hours she worked. Which makes sense—it probably is in Dunkin' Donuts' best interest for us not to know how they treat their model employees.
