Cooperative education is a form of work-integrated learning that includes both classroom study terms and paid work experience. Prior work has studied the benefits of cooperative education for students, employers, and academic institutions. In contrast, this article studies the impact of co-operative education on students' mental well-being. This is done by mining the Reddit social media platform, which includes, among many other topics, discussion communities for major U.S. and Canadian colleges. This analysis reveals that students report feelings of self-doubt resulting from a competitive co-op job market, especially when placed in entry-level jobs that are not related to their academic programs, and anxiety due to job interviews, especially when they coincide with exams and other academic deadlines. Additionally, recent discussions frequently point out cancelled work terms due to the COVID-19 pandemic, creating even more competition, financial hardship, and pressure to make alternate academic or employment arrangements.
