Tendering My Resignation

I quit my job today. Here is the letter of resignation I gave my boss:

Please let this letter signal my resignation, effective immediately, from Jaffe & Nohavicka / Country-Wide Insurance Company. A number of factors have necessitated this change. First, it has become clear that the legal field does not suit me. There is a degree of futility within the No-Fault framework, and within Country-Wide itself, that is simply hard to abide. Further, a simmering antipathy between management and support staff as well as an overall dysfunction of communication has rendered the work environment unpleasant.
While my resignation may seem abrupt, I am merely providing the company with the same courtesy it provides to those it terminates, regardless of whether they’ve served 10 years or 10 months.

I thought it wasn't half bad.
