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 services put together a listing of what is available locally. For some students these part-time jobs could lead to full-time work after graduation as they may offer experience in their own fields, be that finance, marketing, or even management. For example, National Savings Bank offers work on a half time basis: that’s twenty hours a week. Retail stores and restaurants have positions requiring fewer hours, even less time for diose providing child care. We have a number of families registered with us who are looking for babysitters for as few as four hours a week. For students who prefer outdoor work, there are seasonal positions right on campus working with the gardening and landscaping teams. Those often require the most time and are die least flexible in terms of scheduling. To see a complete list of these and other available jobs, including the salary offered and the hours required, stop by our office. In addition, our counselors will give you hints about successful interviewing.
