Burnout is a psychological term referring to long-term exhaustion and diminished interest resulting from chronic workplace stress. It can cause physical, emotional, psychological, and spiritual damage. Burnout develops gradually over time from unrelenting stress at work due to factors like unclear job expectations, lack of control or recognition, and an unsupportive environment. Warning signs include feeling drained, developing health issues, and becoming cynical or detached. Preventing burnout requires reducing stress through healthy lifestyle habits, setting boundaries, and addressing issues directly with employers.
