From the "Birmingham Sunday Mercury" (1/7/01):
Worker dead at desk for 5 days
"Bosses of a publishing firm are trying to work out why no one noticed that one of their employees had been sitting dead at his desk for FIVE DAYS before anyone asked if he was feeling okay.
"George Turklebaum, 51, who had been employed as a proofreader at a New York firm for 30 years, had a heart attack in the open plan office he shared with 23 other workers. He quietly passed away on Monday, but nobody noticed until Saturday morning when an office cleaner asked why he was still working during the weekend.
"His boss, Elliot Wachiaski, said, 'George was always the first guy in each morning and the last to leave at night, so no one found it unusual that he was in the same position all that time and didn't say anything. He was always absorbed in his work and kept much to himself.'
"A post mortem examination revealed that he had been dead for five days after suffering a coronary. Ironically, George was proofreading manuscripts of medical textbooks when he died."
You may want to give your coworkers a nudge occasionally.
