I've only had a chance to get a preliminary look at the document. I noticed that these were the organizations who conducted/funded?/endorsed the study.
The Food Labor Research Center at the
University of California, Berkeley
and
The Food Chain Workers Alliance
& The Restaurant Opportunities Centers
(ROC-United)
Who exactly are these organizations? Looking at their webpages, this is the information on these organizations:
The Food Labor Research Center at the
University of California, Berkeley
The Food Labor Research Center was launched in fall 2012 by Saru Jayaraman as a project of the Labor Center at the University of California, Berkeley. As a leader in the movement for food worker justice, Saru saw a gap in the study of the intersection of food and labor. While there are several University centers that focus on labor studies, and others that focus on food studies, the Food Labor Research Center at the University of California, Berkeley is the first academic institution anywhere in the country to focus on the intersection between food and labor issues in the U.S. and abroad.
The Food Chain Workers Alliance
The Food Chain Workers Alliance is a coalition of worker-based organizations whose members plant, harvest, process, pack, transport, prepare, serve, and sell food, organizing to improve wages and working conditions for all workers along the food chain. The Alliance works together to build a more sustainable food system that respects workers rights, based on the principles of social, environmental and racial justice, in which everyone has access to healthy and affordable food.
The Restaurant Opportunities Centers
The mission of the Restaurant Opportunities Centers (ROC) United is to improve wages and working conditions for the nations restaurant workforce. We are 10,000 restaurant workers, 100 high-road employers, thousands of engaged consumers united for raising restaurant industry standards. - See more at:

These are the authors of the study:
Chris Benner is an Associate Professor of Community and Regional Development
at the University of California, Davis.
Saru Jayaraman is the Director of the Food Labor Research Center at the
University of California, Berkeley and the Co-Founder and Co-Director of the
Restaurant Opportunities Centers United.
I'll still go through the rest of the document, but already, this study seems to be overly biased just like how cigarette companies sponsor cigarette studies back in the old days.
