I was actually surprised when I was at Colgan that there were no probationary reports on new FOs.
However, reports such as these are not the proper form of handling underperforming crew members. It is just another way of management trying to get crew members to rat on one another and do their dirty work for them.
As you will soon find now that you have ALPA, the best way to handle difficult or dangerous crew members is through Pro Standards. Use it. It's good and effective, and keeps the company out of it, unless the situation really and truly warrants it.
