I have a friend that started class recently at PSA. The company wants the classes full and it's understandable that people will no show or cancel at the last minute. My friends class was "over booked." The capacity was 25 and 28 showed up. The company asked for 3 volunteers to take the next available class. The guys that took the offer kept their seniority from the first scheduled class date and were paid full guarantee and perdiem while they were waiting at home for the next class in weeks. The point is, classes are full at PSA and the company is taking extra steps to make sure of it.
