In Wisconsin, most employers are required to carry workers compensation insurance, or be self-insured in the event an employee is injured during the course of employment. Workers compensation is not a fault-base system. If you are injured at work, regardless of fault, you may be entitled to compensation.  If you are injured at work . . . the first step is to report the injury to your employer. This report must be made within 30 days of the injury, and should be made at the time of the injury, if possible. If the injury is caused by exposure, such as carpal tunnel or hearing loss, you should report it as soon as you are informed by your doctor that work exposure may be the cause of the injury. After your report has been made, you have up to 12 years from the date of the injury to request a hearing, however, in most cases a denial of benefits should be contested as soon as possible.
