How do I avoid legal repercussions for writing a story based on events in my life?
Mainly, I have experienced events that I would like to share with the world. These events are somewhat disturbing and would expose the truly spiteful side of an individual who has impacted my life in ways that have only made me stronger. I do not plan to focus on that individual, rather on the way my life was altered (and a big portion due to this individual's actions). This story would cover the struggle faced by women (by other women), culture and religion in the workforce.
Now that I have moved on, I continually recount my experience verbally and feel as though it would do better to spread the message and make an impact through the use of the written word.
How can I accomplish this?
[Edit: The legal repercussions I refer to include those from the individual, perhaps even the company that I worked for even though they are in no way at fault (except for having such an individual on their payroll).]
