Mayor Rahm Emanuel closed the 2018 One Summer Chicago (OSC) job season by thanking youth at BUILD Chicago. BUILD was one of nearly 2,000 work sites that provided a record high 32,000 jobs and internships to youth ages 14-24 this summer, more than double from when the program first began in 2011. The six-week program provided youth with valuable work experience while keeping them safe and engaged during the summer months. This summer youth worked on a variety of projects ranging from building mobile libraries, to working on neighborhood beautification projects, to participating in tech internships and more. BUILD is one of several organizations to receive a mobile community library as part of the new OSC Block Club, Book Club program.  In addition to the mobile libraries, OSC youth have been hard at work this season helping to beautify neighborhoods throughout Chicago.
