Why cooperative workplaces boost your sense of freedom
Jack Welch, the legendary General Electric CEO, was infamous for firing the bottom 10% of his workforce every year, without exception. The company's market cap rose substantially during Welch's tenure, but his "rank and yank" ritual was divisive. If you knew your job was always
