As owner of a small biz, how do I address two junior employees who were given a project to complete, but did a terrible job executing the task? I sent a whistle from CA to OH. Supposedly USPS ripped 1/3 of the entire letter. Miraculously, both our addresses were legible and the postage was still on but only small signs of a delivery date were stamped on the letter. Two of the stamps are lighter and it looks like she Photoshopped it. How can I find out?
