Office desk jobs are not meant for me. My boss told me off and said that he will terminate my labour contract if it happens again today. I believed that my coworker/coworkers told him about me falling asleep on my desk. I can’t help it. The environment is dull. Imagine sitting and looking at the screen for 8 hours everyday. I don’t really talk to my coworkers because they’re always gossiping. I can still fall asleep despite the loud chit chat. Caffeine doesn’t seem to work for me. Are there some kind of medication I can take to stay awake while working in the office?
