Vantaggi
PTO time. If your lucky enough to have good direct management, they will be very flexible. Holidays are off. Overtime is possible if the client needs project work. Online classes for certifications if one chooses to take advantage.
Svantaggi
Many cons to report which is a very sad truth. You will strive to be the best and advance yourself only to be knocked down even if you have received good yearly reports. I have learned that the company uses "the economy is bad" approach on just about every financial decision that could benefit you as an employee. No raises in the past 4+ years, change in benefits every year which end up costing the employee more money, 401k match consistently gets smaller every year. Micro management by groups the company hires to find ways for to increase productivity.
