I appreciate the honest feedback. I say hello to a lot of my co-workers as well. The issue isn't about being friendly, I always say hello..it's about actually engaging in a conversation that i'm lost in. I guess I should disclose the fact that I stutter, for whatever reason I have not. I interact with my managers whenever they need something of me, as I work in a huge warehouse and they walk around 24/7. Some of my co-workers are constantly making small talk with the managers during the shift. Like I said, small talk is difficult for me. I do understand why they approach those employees for things more often, it's human nature to approach those you feel more comfortable with. Thank you though I appreciate you taking the time to reply.
