this is what ive been told from others who are currently working for MAM. you will get a guaranteed of 80 hours a month. it could be a mix of flying duties and home reserve, or even a whole month of home reserve if its a slow period. but remember, you will get paid for those home reserve (4 hours so about $120 or more).
so to answer your question, if they don't need you for flying duties, then yes they wont pay you because you are not working, but to make up your hours of 80 hours a month, they will most probably put you on home reserve, which then you will get paid even if you don't get called out.
so don't worry about it because im sure you will be fine financially =)
