The business writing I found online is a letter of termination. As I read the letter, I noticed how the first paragraph is not sincere. The writer, who is the manager, used words such as regret, and terminated. However the rest of the letter is very sincere because this company is firing this man for economic reasons, not because he is a bad worker. The manager follows the letter with six more weekly pays after he gets fired and he is able to keep his dental and medical insurance until the end of the period. The manager also offers the worker a recommendation letter if he ever wants one.
Over all, I think this is an effective way of writing. The manager apologizes for firing this worker, and he then offers temporary benefits after his termination. The manager makes this letter all about the receiver which is very effective.
