I personally can understand Walker's frustration. First of all, he wasn't happy with being a back-up in 2004. However, even when he admitted he didn't play as well as back-up, he said it was the situation he signed on as and said that he wouldn't do it again. When he signed his current deal prior to the 2005 season, he signed to be a starter. Those were the promises made to him and he started in 2005. He had an option for 2006. Since he signed the deal with the expectation that he would start, he likely believes, and rightfully so, that if the Cubs picked up the option it would be with intentions to let him start. In his mind, if the Cubs aren't willing to do that, they should have declined his option and let him seek employment on his own terms. My guess is that since his option was picked up and he is not named the starter and that he had to endure trade rumors, he's not as happy with the organization as he would like. While some may call that unprofessional, is it not just as unprofessional to go back on your word---even if that isn't done out in the open? Also, while some have compared Walker's mouthing off to corporate America, it isn't the same thing exactly. If this happened in corporate America, the worker could suffer damages by being terminated. Walker, while he might get released, would still collect his check. He is free to mouth off if he wants without compensation. I'm guessing if many in corporate America had that security as well as an audience as Walker has, they would mouth off about wrongs at work as well.
