Banging your head is downright dangerous and a surefire way to wreck a worker’s day and rack up unnecessary costs. According to the latest Bureau of Labor Statistics data, head and neck injuries are the third highest cause of work-related emergency room visits. Not to mention, a head injury is the most costly injury in terms of workers’ compensation, with an average cost of more than $85,000.

Put those two stats together and you get one very large sum.
