Research suggests that weight discrimination permeates the American workplace. A recent Harvard study examined how biases change over time. Researchers examined data that was collected over nine years and measured implicit and explicit biases. The results suggest that while unconscious bias against race and sexual orientation has decreased over time, implicit bias against high-weight people have increased.
Despite studies showing that these negative attitudes are having an impact on high-weigh people in the workplace, discrimination against them is still legal in 49 states. Michigan is the only state that has passed legislation that makes weight discrimination explicitly illegal.
