Of course it does. Notice is a very good custom not a principle of law. Even if I hated an employer, I would not leave without giving notice.
It may not be long before the liberals fix all law and custom and then we serfs and our children will work for who, where, when, why, what and how they say we will according to their infinitely benevolent will:
"The Obama Administration will call on Americans to serve in order to meet the nations challenges. President-Elect Obama will expand national service programs like AmeriCorps and Peace Corps and will create a new Classroom Corps to help teachers in underserved schools, as well as a new Health Corps, Clean Energy Corps, and Veterans Corps. Obama will call on citizens of all ages to serve America, by developing a plan to require 50 hours of community service in middle school and high school and 100 hours of community service in college every year. Obama will encourage retiring Americans to serve by improving programs available for individuals over age 55, while at the same time promoting youth programs such as Youth Build and Head Start."
I believe in turn-around as fair play.
