Nearly one-third of US workers don’t get paid sick leave, and it might not surprise you that those workers are more likely to have incomes below the poverty line. But it’s a little more surprising when that correlation holds up when controlling for education, race, sex, marital status and—most importantly—employment. In fact, those workers are three times more likely to have poverty incomes than peers who do get paid sick leave, according to new research by Florida Atlantic University and Cleveland State University. The study authors attribute the income gap to lack of preventative care, missed wages, and everyone’s favorite social ill—the rise of healthcare costs. If you’re sick and still have to show up to work, hopefully these sick memes can help you out.
