I worked at milestones last summer and again this summer. I was hired as a re-hire, same number, same position, same salary. I was pulled into the office after work for 2 months. My boss told me I have been messing up a lot lately and they don't see the point in investing time in me. I have never been written up, talked to about messing up, or forewarned. I drove to work for my 5pm shift and was dismissed upon arrival. I have passed my 3-month probation. I have never had a complaint. Is this right ?
