I put in my 2 weeks notice months ago, but I still look back at my Starbucks days because I realize I was immature at times and I don't know how to improve.

I rarely dealt with very bad partners. But sometimes I felt like a coworker had treated me poorly, and I let that resentment grow within me instead of communicating openly. In other words, I'm petty. And I really hate it.

One time, I did speak up to a coworker who seemed to treat me coldly. I found out he never intended to act a certain way toward me at all - he was just struggling with issues at home, and he was trying his best to keep up a friendly demeanor. That was one example that stood out to me: that open communication is the mature decision if you want to speak up and bring attention to something.

But I'm discouraged. Sometimes, I don't really know whether I should say anything: maybe I'm just too sensitive and get easily offended. Not to mention undesired/unintended results, such as a chatty coworker who may choose to gossip and say things like "computernoobe is such an annoying baby.. he'll get hurt by anything" behind my back or yada yada.

This isn't really relevant to your post and I apologize. Just something I've been thinking about recently.

And then we all get downvoted..

someone felt attacked.

Yes. It is disheartening & can lead to shifts being strained. Attempting to avoid said partners doesn't help either.

I'm very sensitive & know that, but a partner crossed a line recently toward me that I felt would have been hurtful to anyone & I did decide to report it.

I'm now nervous about what may come from reporting it but only time will tell.

Yep. Dreading going in today for this reason.
