You don't need to write a novel with these. Also, writing an email about how you're going to can a bunch of people over the coming year and then droning on about how the results of that are going to be so much better (and insinuate that the current setup, which is 100% a management failure, was a poor setup) is insulting.
Also, this is a 2nd round barely 6 months after the first and it's going to happen over months. This will be great for morale and will likely only cause your A players (who are probably still very much in demand) to look elsewhere.
Could not disagree more. Researching, formulating arguments, can give a student a complete view of the subject that studying for tests misses. But, similarly to tests, it probably depends on the skill of the teacher in creating the right kind of written assignments.
