I don’t envy the job sport referees, umpires and judges have. They must make split second decisions under pressure, and they make them numerous times in a game.
Being able to make these decisions is a burden unto itself. Faced with two teams on the field, the umpire must be the principle instigator of ensuring said teams play the game in a fair and sportsmenlike manner. At times you are faced with player arguments, heated battles and a lot of noise directed towards you.
