Judging by the comments I think it's safe to assume that the "taking responsibility" part is a meaningless statement at best. What I want to understand is does he even owe anyone an apology? Isn't employment just an agreement to provide services in exchange for money and benefits? Anywhere I work I expect my employer to fire me the moment they don't need my services or find a better/cheaper alternative, I wouldn't think twice if I found a better employer. So why would I be owed an apology or someone to "take responsibility"?
