What This Course Is About

            Work is an integral part of our society and all societies.  On the large scale, we depend on one another to produce food, shelter, and other basic necessities. Work also shapes how we see ourselves and others. Have you ever wondered what determines job satisfaction, why companies organize work in the way that they do, or why housework is not financially compensated? Our own work, and the work of others, influences everything we do.  In this course, we will examine how and why we work in order to gain a better understanding our society.

            This is an exciting time to be thinking about work and labor in America.  The nature of work and workplaces is changing rapidly due to changes in the global economy,  technology, politics, and social movements.  Questions of business ethics and corporate responsibility, labor unrest, sweatshops, income inequality and the “Wal-Martization” of society, and related matters are in the news.

            Work occupies our best waking hours. The nature of our work is the most significant factor determining of the quality of our daily lives. This class will help students understand the varieties of work and its future role in their lives. We will examine such questions as: "Why are there no easy jobs?" "Why do we have increasing problems of low-wage work in a wealthy society?" "What do people mean when they say that the U.S. has become a  service economy?" "Are women gaining more equality at the workplace?" “Are racial minorities gaining more equality at the workplace?”  "What are your chances of getting injured or sick on the job?" "What does the changing world economy mean for your future?" “How can you balance career and family responsibilities?” and, "What can you do to make the world of work a better place?"

            There are three main objectives for this course:

            1. To provide an understanding of how people experience work and the workplace in everyday life.

            2. To understand the ways in which social inequality is reproduced in the world of work and to learn more about the struggles of workers to bring about change in overall inequality as well as work and workplaces..

            3. To prepare you for work in terms of thinking about what kinds of jobs you’d like to pursue, how these jobs and workplaces contribute to society,  and what you can do to maximize your ability to find a job that is rewarding and a career with a conscience.

 

Keeping in Touch with Me

 


            My office hours are Tuesdays and Thursdays, 1 to 2:30 pm in UEPI. If this time slot is inconvenient, I am very happy to make an appointment with you. I encourage you to visit me during my office hours if you have any questions or problems with the readings or other assignments, or if you’d just like to stop in and talk. Check your email every day. I frequently email the class about assignments and other matters. My email address is:

 

Course Requirements

 

I expect that:

 

o You will come to class each day on time, having done the reading assignment and prepared to participate by asking and answering questions and by expressing your opinions.

o You will ask questions about anything you don't understand. I expect that written assignments will be done and turned in on time and that they will reflect the best work you can do.

o You will contact me if you are having any problems in the course or if you are having personal problems which may affect your performance in the course.

o You will work hard at getting the most out of this course that you possibly can.

 Grades

1. One-third of your grade will be based on your attendance and participation in class. Your class participation is important, especially in a class like this where we will be discussing difficult questions with no easy answers.

2. One-third of your grade will be based on writing assignments. There will be between five and six writing assignments. All will be between three and five pages. Some will be individual assignments. Others will be group assignments for which each member of the group will receive the same grade.

I encourage all students to take advantage of the CTL to get help with your writing. Everyone can improve their writing.  It helps to do an outline, then a draft, and show it to the CTL and/or to me before submitting your final version to me.  I do not accept late papers except in cases of extreme family or medical emergencies.

3.  One-third of your  grade will be based on a take-home final exam. This will be an essay-style exam. It will cover the entire course.

Extra Credit: Short Research Paper

            Students who want to improve their grade, and/or who want the experience of writing a research paper, can get additional credit by writing a 10-12 page paper on a topic involving work. If you get an A or A- on the paper, I will increase your final grade by one entire grade (i.e. from B to A). If you get an B or B+ on the paper, I will increase your final grade by one half grade (i.e. from B to B+, or from A- to A).  If you want to choose this option, you must meet with me at least once before Tuesday, February 17 to discuss your topic and your research strategy. You should have at least a rough idea of what you want to write about when you come to see me. The paper can be based on interviews, on observations, on library research, and other approaches. It can be about a particular industry, a particular occupation, a comparison of jobs, an event in labor history, a current issue in labor-management relations, an analysis of the treatment of labor and work in the media and films, or any other topic, so long as I approve it. A draft of this paper is due on Tuesday, April 20. The final paper is due the last day of class.
