I work for an air hub. Guranteed 3 hours per contract but usually get about 2 hours of work. We can leave once all feeder planes are gone or push a broom for an hour. Recently got my vac check and was shorted by about one hour. I was told that I did not work my full 625 hours to qualify for full 20hrs of paid vac. I was also told that my holiday hours, vacations hours, option day hours do not count for hours worked. Is this right?
