Workplace burnout is a syndrome of emotional exhaustion, feelings of reduced personal accomplishment, and cynicism related to one's job. It can be caused by excessive job demands, role ambiguity or conflict, lack of resources or social support, and personality traits like perfectionism. Signs include physical exhaustion, frequent illness, detachment, loss of motivation, and negative outlook. Severe burnout is characterized by inability to get up in the morning due to exhaustion, excessive workload preventing recovery, cynicism where the job seems meaningless, and emotional drain from intense work without replacement of drained resources. Preventing burnout requires reducing stressors, increasing support, setting boundaries, and practicing self-care.
