"Jobs had not tempered his way of dealing with employees. "He applied charm or public humiliation in a way that in most cases proved to be pretty effective," Tribble recalled. But sometimes it wasn't. One engineer, David Paulsen, put in ninety-hour weeks for the first ten months at NeXT. He quit when "Steve walked in one Friday afternoon and told us how unimpressed he was with what we were doing." When Business Week asked him why he treated employees so harshly, Jobs said it made the company better. "Part of my responsibility is to be a yardstick of quality. Some people aren't used to an environment where excellence is expected." But he still had his spirit and charisma. There were plenty of field trips, visits by akido masters, and off-site retreats."
