Even the best professionals can act unprofessionally. They would never give you what you have rightfully earned. No matter how hard you have worked for it. No matter how deserving you have proven yourself to be. It’s not okay. But you just have to get along and go on doing your best. “The reward of our work is not what we get, but what we become.” (Coelho, 2012)
And what you could be by doing your best is enough to make them pay.
