Honestly, can you guys let me know what you think of this letter I am giving to my employer (for those who didn't read the long-winded post, I am having difficulty with a coworker/actually staff member. I just want to make sure this is clear, concise, and leaves no doubt that I am serious about the threat. I am, admittedly, also trying to cover my own butt if s*** hits the fan and/or I quit. PLEASE give your honest opinion. I have never done this before and actually feel a little silly doing it, but I have been reading up on the warning signs of workplace violence since someone brought it up and I actually am getting pretty scared. My H of course is thinking I should be more worried about a potential lawsuit from this woman, but I KNOW I didn't do anything wrong! That is what is most frustrating. Anyway, here is the letter, please let me know what you think!

In light of recent activities in the office, I am very concerned for my safety and for the safety of the employees in the Upper Marlboro office of Weinstein Eye Associates. Sherry Clarks erratic and hostile behavior when an issue is brought to light in which I need to speak to her, such as regarding errors she has made, makes me nervous interacting with her. Each time in the past that an issue has been discussed with her, regardless of the nature of the discussion, Sherrys histrionics and threats make rational discussion impossible. I have had multiple discussions with other employees in which they have clearly registered concern over her comments regarding purchasing a gun and learning to protect herself from threats, coupled with her erratic and often overly emotional behavior toward management and other employees.
I have tried to speak with Sherry gently regarding some of the concerns I and others have regarding her escalating mistakes and increasingly odd behaviors, to no avail. In desperation I requested that my practice administrator step in and assist me with trying to uncover the root of the problems so that we can remedy them and move on productively. Unfortunately, that meeting deteriorated quickly into threatening and accusatory behavior on the part of Sherry Clark and the final result was that Sherry was offered the opportunity to go home by Dr. Weinstein in light of her emotional disturbance, which was causing discomfort with the other employees and the patients. Naively, I assumed that all would return to normal following this display and perhaps with a gentle conversation that evening, as she typically contacts me when these episodes occur and I am able to coax her into acknowledging that her perceptions are in fact distorted and that nobody is out to get her or targeting her as she believes.
I am concerned because Sherry Clarks erratic behavior appears to be escalating. I have been receiving messages from Sherry implying that she feels that Tammy was abusing her and that I set her up to be abused. I fear that Sherry, in her emotional state, is dangerous in light of statements she has made repeatedly to myself and others in the office, on multiple occasions, regarding the fact that she now has a gun, is trained to use it, and will go to great lengths to protect herself. I feel that this, coupled with her current emotional state, could represent a potentially dangerous situation for myself, Tammy, and indeed for the entire staff of the Upper Marlboro office.
I am in fact uncomfortable with the fact that Sherry Clark is being permitted to return to work following this obvious display of emotional instability and threatening behavior toward myself and Tammy. I have had multiple conversations, as well, with other employees in the Upper Marlboro office who are also concerned about her behavior and have expressed a desire not to work with her again. They are, in fact, discussing the locations of the panic buttons and how quickly police will respond to the office should the unthinkable happen and Sherry appear at the office with the intent to shoot someone. I have to concur with them that I am uncomfortable working with her again in light of her behavior, and that I am also in fear for my life and theirs as this situation has been all too common in recent timesschool and office shootings. I have not been sleeping well and this situation has caused me tremendous distress.
