There are many stories of disgruntled workers returning to their former workplaces and killing people. Or at least threatening to do so.

In March 2007, Michael Hiner was fired from his job at Grand Caverns. Hiner returned later in the day to confront his ex-boss with a gun. In order to help explain how to handle these kinds of situations, several organizations including the Mental Health Association of Augusta held a seminar called Mental Health in the Workplace on Tuesday.

Amy Ghaemmaghami with Augusta Medical Center says there are ways a situation like that one could have been avoided.

She says, "Observing the behavior, documenting, making a referral and knowing your policy at work and having then a safe environment for that person to vent, to recover, whatever their need is."

Tom Rose with the Valley Community Service Board came to the seminar. He says it's important to learn about depression and other mental illness so employers can spot warning signs if an employee is upset.

"As an employer and human resource managers, it's our responsibility to see what we can do to better benefit our employees and help them through a certain situation," says Rose.

Ghaemmaghami says it's all about communication between employer and employee.

She says, "To decrease chances of a violent incident, you have to have people understanding their task and understanding their relationship and the more value they have on the task and the more value they have on the relationship, the better chances of a collaboration."
