The cadets get no pay until the safety pilot is released after 12 or so sectors of line training, and as zero-hour contractors, they are only paid flight pay with no salary anyway. So, they would indeed be unpaid for their ground school and sim training, and continue to be unpaid for all recurrent training and ground/sim checking, and also have to pay RYR several hundred Euros for those days until they can get a permanent position (usually gained with commands).
