Vantaggi
The pay is only good when you are regular on the field. But then, that isn't often. You get to travel to different countries.
Svantaggi
Top management seem not to have records of employee which means promotions are done on requests, good friends or nationality with top management. In a world where nothing is perfect, you get no protection or support from management when the client starts being angry and field staffs are often left to face the brunt of the client alone. The field staffs are always to blame for most negative things on the field when management has failed to give enough support to field staffs. Training is poorly organized and most of the time you have to literally beg for it. You are expected to perform magic when you don't have all your tools. Whenever you send mails to your boss especially when you are home and activites are low, your boss hardly responds to your mails. Top management have more trust in the client and what the client says than in their own employees. Switching departments is almost impossible, I wonder how the phrase "one weatherford" was coined.
