Making plans for summer vacation? You are probably wondering whether you are too busy to take a week off from work. The thought of being away from the office probably makes you a bit nervous. After all, how will they get along without you? You are not the first person to consider what not to pack to make room for your laptop. We convince ourselves that our work contributions are so absolutely essential that our organization will fall apart at the seams(崩溃) if we are away, ignoring the interruption to our personal lives, much less the disagreeable effect on our colleagues. It is the indispensability syndrome: an inaccurate emotional urge rooted deep in our desire to be wanted and needed. We feel threatened by the realization that our working world can continue without us. It is a perfectly natural feeling, but it comes at high cost. One executive I worked with had been promoted to a partner at a mid-sized government consulting firm two years ago. Only 35, his ambition and work ethic pushed him quickly through the ranks. He was known as a perfectionist whose work reflected the very highest standards. The firm required all partners to take a two-week vacation every two years. The idea was to step back from the routine tasks and come back rested and recharged with innovative ideas about how to advance the company’s practice. Associates were expected to assume all responsibilities during a partner’s absence. But during his vacation, this young partner emailed and texted his associates multiple times daily and directly contacted clients for updates ― even though doing so was explicitly prohibited by firm policy. The result: Four of his 10 associates requested transfers. He was severely warned that his behavior was unacceptable and would negatively affect his annual performance review. He learned the hard way that he wasn’t indispensable. According to a 2013 survey by the American Psychological Association(APA), more than half of all employed adults say they check work messages at least once a day over the weekend, before or after work during the weekday and even when they are sick. More than 40% reported doing the same while on vacation. My own research, conducting interviews with 127 executives from 17 countries, suggests that the APA’s findings would be amplified (放大) if focused on senior corporate employees. When asked how important their contributions were to their unit or team, all of them responded "very important". When asked how important their contributions were to their unit or team compared with others, 76% responded "more important" and 24% responded "as important". None said "less important". When asked how uncomfortable they’d be if they had no contact with their organizations whatsoever for two weeks, 72% said "very" and 20% replied "somewhat". Only 8% responded that they could part for a while with no worries. Part of this can be traced to technology. Thirty-six percent of employed Americans said communication technology increases their workload, making it more difficult to stop thinking about work or take a break from work, the APA survey reported. This behavior can cause a change in both us and our colleagues. If we distort (曲解) our own importance, then we reduce the value of others. By doing so we hold back the people who work for and with us, rather than help them stand on their own. That isn’t leadership. We’ve accomplished what we have for a reason, so there’s no reason to worry that our capabilities will be forgotten after a week or two of vacation. If we accept the fact that we are not quite as important as we think we are, that all of us need to be off from work in order to refresh and that our constant involvement is not always beneficial to colleagues, we are more likely to take a vacation, and will, in turn, make greater contributions at work upon our return. 1．Why does the author mention the executive he worked with?
