Command Training Bonds
I'm with DAH on this one. It is becoming the norm for companies to have training bonds for Command courses. Especially if the training involves Sim work. In this day and age Sim's dont come cheap and the companies are only trying to protect their investment.
That said, a training bond should not be an issue if you are willing to take the upgrade and happy to stay with the company. Of course how much the bond is and for how long have to be realistic. (I have no idea what link is preposing)
Bottom line: Do you want the upgrade and are you going to stay, or just use the company and then do a "runner".
