I've been working as a summer intern at an arms manufacturer in Georgia for the past few weeks and a couple weeks back an email was sent to me and every other intern about a monthly bonus. I checked my bank the week after to see that I hadn't been paid the bonus so I asked my fellow interns If they had received the bonus. While two of the other interns I had talked to didn't get the bonus one did get the bonus and another bonus that I didn't know about from weeks earlier. When I asked the HR department they said that no interns got the bonus and only full time employees got the bonus. Not only have I been working full time the whole time I've been here but another intern with the same title and position as me did get the bonus. Can I do anything or am I shit out a luck?
