Not getting enough sleep isn't always seen as a valid excuse like the flu, but it can be a good reason to miss work if severe sleep deprivation makes you unsafe or unable to perform your duties, similar to being medically unfit; however, many experts suggest calling in "unwell" or "not feeling well" instead of specifying "tired," as it's more professional and avoids appearing unreliable, with chronic issues potentially warranting a doctor's note for sick leave.

Can I call out of work for no sleep?

Yes, severe lack of sleep is a valid reason to call in sick, especially if it impairs your ability to function safely or effectively at work, similar to a migraine or fever, impacting focus, mood, and concentration. While an isolated poor night's sleep might not always warrant a day off, persistent insomnia or extreme fatigue that makes you unfit for duty (especially in safety-critical roles) is a legitimate health reason to rest and recover, though honesty about the cause (e.g., fatigue, mental health day) is best. 

Should I still go to work if I haven't slept?
