One of world's most successful business leaders, Elon Musk, has said that people need to work from around 80 to over 100 hours per week to "change world". Mr Musk knows what he is talking about because he has his finger in many pies. He is founder, CEO and lead designer of SpaceX; co-founder and CEO of car company Tesla; and the co-founder of PayPal. He works very hard on many projects that have changed and could change our lives. He said he is workaholic but he loves what he does. He talked about working hard in interview with technology news website Recode. He said: "There are way easier places to work, but nobody ever changed world on 40 hours week."
It is not just Mr Musk who works hard. Workers at his companies also put in very long hours. Musk said "everyone" at Tesla has worked 100 hours per week at times this year. He said this was necessary to make sure Tesla Model 3 car could survive. He said: "There wasn't some other way to do this." Musk acknowledged that some Tesla employees were unhappy with working so hard. He said some workers called hours "excessive," while others said they prefer to work 70 or more hours per week. Musk said "pain level" of working hard increases above 80 hours week, but he didn't say what pain was. average CEO of multi-billion-dollar company works around 70 hours week.
