@Tibalt_Ablaze other than receiving texts about it, you were not involved in the incident, right? You shouldn't need to worry. But express to your coworker that you need/want your job and you don't want to be pulled into the middle of something that isn't about you. If she is a good friend she will respect that. If it does escalate with the manager and you are pulled into the conversation reiterate that you were not involved and that they texted you about it only. There should be no reason for
@MotherDucker thanks I don't work with this co worker for sometime but if they do text me I will let her know. this is between You and the manager, I no longer want to be in the middle of this. if you don't want to talk to me other then at work ( if she doesn't get fired or quit) I am ok with it but I am done.
@Tibalt_Ablaze the manager to initiate any corrective action for you.
