No, you cannot pay your employee close to nothing, give them no hours, push them to hard everyday to reach impossible deadlines and expect to keep them. If you keep changing everything while showing no appreciation to the employees which are having do implement the change, the employee will not stay with you. If you treat your employee like crap to save literally twelve dollars, you will not have good employee retention. Before long you are company that lacks focus with employees that only stay with you because they are incompetent and unable to find better jobs.
