I've only been out of college and into the workforce for 3 years yet I feel as though I have sufficient vacation time (2 weeks + 11 holidays) per year. At times I feel that I have too much vacation in the standpoint that my vacation time rolls over to the next year. Even though my vacation time when I was in school (3 months) was far more greater than in the working world, I feel that too much vacation time will logically yield less hours put into a job and therefore a productivity yield that is low.
I personally only get three weeks vacation time and I do not think that is fair at all. Sometimes I think it would be nice if we could have at least a months worth. That way I could take an actual vacation as well as be able to relax and enjoy time with my family.
