How to avoid workplace harassment lawsuits
Make a strong statement against harassment.
Begin any written policy with a strongly-worded statement that your company has no tolerance for harassment in the workplace.
Harassment includes any conduct that creates an offensive, intimidating, or hostile work environment.
Even without complaints, it only takes one out-of-line employee to create a permissive environment where harassment seems acceptable. Embody your stance against harassment in a written policy that reassures employees that such activities are not tolerated and that complaints are taken very seriously.
