Spot does what Spot needs to do stay in the game.
That being said, over scheduling days is an abusive practice. It covers up problems of insufficient pay/hiring practices created by a failure to adequately plan. It's a leadership problem that often plagues retail as no one feels empowered to push back upstream against policies that cause the problem.
Spot does a horrible job at time management. Ironically the most important detail in our profitability.
