As a result of rising university costs, many students are finding it necessary to take on part-time jobs. To make finding those jobs easier, the placement service has put together a listing of what is available locally. For some students, those part-time jobs could lead to the full time work after graduation, as they may offer experience in their own field, like finance, marketing or even management. For example, national savings bank offers work on a half time basis. That’s 20 hours a week. Retail stores and restaurants have positions requiring fewer hours. Even less time is expected of those providing child-care. We have a number of families registered with us who are looking for baby-sitters for as few as four hours a week. For students who prefer outdoor work there’re seasonal positions right on campus, working with the gardening and landscaping teams. These often require the most time and they are the least flexible in terms of scheduling. To see a complete list of these and other available jobs, including the salary offered in the hours required, stop by our office and be sure to bring a resume with you. When you find something that interests you, we’ll put you in touch with the person offering it. In addition, our counselors will give you hints about successful interviewing.
