The hazard
Everyone brings their life to work: money worries, family problems, long hours, time away from home, grief or a layoff. Stress, burnout, anxiety, depression and substance use are health problems, not weakness, and people do get better with help. They also pull your focus off the task, and on a jobsite a lost focus can get someone hurt. Looking out for each other's minds is part of looking out for each other's safety.
The action
Pick a private moment and ask straight out: "How are you really doing?" Then listen without judging, arguing or trying to fix everything. If you are worried they might hurt themselves, it is okay to ask directly if they are thinking about suicide. Stay with them and help them connect with support.
