Flight attendants should get paid while they are working

flight attendant has to report to the airport office at least two hours before the flight departure time to finish all the paper works document etc, 

also has to check in 45 mins before the boarding time to prepare and setup the cabin to get it ready for passengers.  

During boarding, flight attendant has to help with wheel chair passengers, kids travel without parents, adults over size and over weight baggage etc. 

BUT, flight attendants  don’t actually get paid until the plane push back.  

Means for all the minimum two hours of work, and no matter how bad the delay is, flight attendants don’t get paid while they are on the ground
