Honestly, I don't know if this is a smart move. My biggest concern is the head of group A will feel betrayed... but he is a very nice guy and he is the president of the company, I hope by doing this I won't offend him; and my intention is to do tasks for both posotions since I have extra time, that's why I call myself crazy...
Anyway, I don't know what to think right now, would like to hear you guys' opinion
