employees often have to depend on each other. When a single employee loafs , others will have to compensate for hisher workload in addition to their own tasks. Students will learn from their working experience the importance of cooperation and why every individual should effectively carry out hisher own work . Another point is that these working possibilities enable the students to understand the value of money and that “Money does not grow on trees”. After the student sees how hard heshe has to work to earn money , heshe will also be more reasonable while spending it . Thus, working helps lead to responsible spending. In conclusion, when one has a job as a student , heshe will benefit significantly from the experience . This way, students will be more responsible when they graduate . Furthermore, they will be more cooperative and better able to work as part of a team. Finally, since they‟ll be cautious about spending their money , they will be less likely to get into trouble due to excessive spending . All in all, having jobs as students is a terrific idea and I think every student should have a working experience before graduating and starting their professional careers . 34
