<human>: Can you give me the gist of the text in a nutshell?

I work at a Meijer (regional American supermarket). A verbal incident with an employee (with their friend present) initiated unintentionally by myself and escalated on their end is making me ask myself if I am legally capable of protecting myself from slander.

The incident was fairly light. An employee felt their hours threatened by my return to work and was agitated because of it. They made some insulting remarks towards me. I brought this incident to the attention of our Store Director and they got statements from everybody individually. The two other parties collaborated their stories and basically made me out as the aggressor. Their word/s against mine. Am I legally allowed to carry a digital audio recorder to protect myself in the future?
<bot>: They said against what I say. They have two stories against mine. Can I carry an audio recorder to protect myself from future slander?
