Mike Isaac’s Super Pumped (p. 171) describes “intense pressure” including “work[ing] late into the evenings.” He continues:
Some [employees] never took weekends off to enjoy time with their families. It wasn’t uncommon for bosses to call employees in the middle of the night, or for staff to be asked to join a conference call at two o’clock in the morning from New York if you were trying to talk to offices in Southeast Asia or Australia.
