Being an information technology, or IT, worker is not a job I envy. They are the ones who, right in the middle of a critical meeting, are expected to instantly fix the projector that’s no longer working. They have to tolerate the bad tempers of colleagues frustrated at the number of times they’ve had to call the help desk for the same issue. They are also the ones who know there are systems that are more powerful, reliable and faster, but their employer simply will not put up the funds to buy them.

        According to a recent survey, employees who have a job reliant on IT support consider IT a major source of job dissatisfaction. Through no fault of their own, they can suddenly find their productivity deteriorating or quality control non-existent. And there’s little they can do about it.

        The experience of using IT penetrates almost the entire work field. It has become a crucial part of employees’ overall work experience. When IT is operating as it should, employee self-confidence swells. Their job satisfaction, too, can surge when well-functioning machines relieve them of dull tasks or repetitive processes. But if there’s one thing that triggers widespread employee frustration, it’s an IT transformation project gone wrong, where swollen expectations have been popped and a long list of promised efficiencies have been reversed. This occurs when business leaders implement IT initiatives with little consideration of how those changes will impact the end user.

        Which is why managers should appreciate just how influential the IT user experience is to their employees, and exert substantial effort in ensuring their IT team eliminate programming errors and application crashes. Adequate and timely IT support should also be available to enable users to cope with technological issues at work. More importantly, IT practitioners need to understand what employees experience mentally when they use IT.

        Therefore, businesses need to set up their IT infrastructure so that it is designed to fit in with their employees’ work, rather than adjust their work to fit in with the company’s IT limitations.

解析：C。根据题干中的a recent survey和employees who have a job reliant on IT support可定位至原文第二段。该段提到，那些自身工作需要依靠信息技术支持的员工认为，信息技术是他们对工作不满意的主要原因。他们没有做错什么，却发现工作效率和质量把控受到了影响，自己却无能为力。C项与此内容相符，其中的deeply frustrated是对原文第二段第一句中的job dissatisfaction和第二段第二句的概括总结，故C项为正确答案。

错项排除：A项和B项分别利用原文第二段中的productivity和quality control设置干扰，但此处是说员工们认为，信息技术支持薄弱会给生产效率和质量把控带来不利影响，A项和B项与原文意思相悖，故均错误。原文中只提到该调查针对的是自身工作需要依靠信息技术支持的员工，并未提到该群体对于信息技术的依赖程度，故排除D项。
