How Leaders Describe a Typical Day at Work

Instructor, Heavy Duty Truck Program ,

College of Western Idaho

Five days a week for four hours a day, I teach a cohort of students theory of diesel technology. I lecture and then we apply the theory in lab through hands-on practice. After class, I grade papers, create new lab tasks and lesson plans, or attend meetings. I'm a CWI senator for the diesel department. This allows me to voice the department's concerns or needs to school officials. I also visit high schools or meet with programs, like LatinX, to share the career opportunities our program offers.
