People die on the job every summer. Remember that water and shade breaks are crucial when working in the heat, and calling emergency services for signs of serious heat illness (fatigue, nausea/vomiting, headaches, dizziness, clammy skin, confusion, agitation, slurred speech, high body temperature, rapid heart rate, etc.) is entirely appropriate. If you’re afraid to call 911 for reasons such as being undocumented, you’ll need to get very familiar with how to prevent, recognize, and treat heat illness. If you are symptomatic and not allowed a break, water, or medical treatment, walk out. No matter how broke you are, your job is not worth your life.
