You can report your employer to Utah's division of OSHA if they did not display workplace safety posters as required by the federal government. As a result, the organization may conduct an investigation and enforce the hanging of these posters or punish your company with a fine. You cannot be punished by your employer for reporting the company in this failing. However, unless you are injured because of this negligence during your regular line of work, you cannot sue your company simply because they did not hang the posters.
