Check whether you can travel and work safely, contact your supervisor or staffing line, and use another ride if needed. A short nap or caffeine may help alertness, but neither makes serious fatigue disappear.
Don't wait until the commute to admit how tired you are
You went to bed after the school run, construction started next door, and sleep never really happened. Now the shift is approaching and calling out feels impossible. Take that pressure seriously, but also take your alertness seriously. A staffing problem shouldn't quietly become a car crash or a mistake at work.
Ask yourself concrete questions. Can you keep your eyes open while sitting? Are you losing track of simple tasks? Would you trust yourself to drive, operate equipment, give medication, or notice a hazard? If the answer worries you, call the appropriate person before you leave.
Use temporary help for what it is
A planned nap, food, light, and caffeine may improve how alert you feel. They aren't permission slips for every job under every level of sleep loss. Follow your workplace's fatigue procedure and be direct about the safety concern. If you go in, arrange transport rather than hoping the drive works out.
If failed day sleep is common, bring the pattern to a healthcare professional and to workplace scheduling conversations. Riso can wake you for a shift after sleep. It can't replace the sleep you never got.
Common questions
Can I call out because I didn't sleep?
Policies differ, but severe fatigue can be a safety issue. Contact the right supervisor and explain your functional concern clearly.
Would a nap before work fix it?
It may improve alertness, especially if planned well, but it may not be enough for severe fatigue or safety-sensitive work.
