The Risk and Insurance Management Society (RIMS) is a great source of information for companies looking to control risk and control business insurance premium costs. The RIMS professional library is a terific way to learn risk and insurance management.
The Society frequently sends me e-mails about product offerings and I do not receive any compensation from RIMS. I mention their publications because I know they are well written and practical.
Workers' compensation is complicated. It is also mandatory. It is also one area of business insurance where proper preparation and implementation of good company policies can significantly reduce premiums. Often very simple bookkeeping or hiring changes can save 15-20% of premium dollars.
RIMS is offering a 2012 publication entitled Workers Compensation Management Program - Reduce Costs 20% to 50% at its store. "The book guides the user through each aspect of a workers' compensation program, to learn, step-by-step about a variety of techniques that show organizations exactly how to reduce workers compensation costs." If your company has a large workers' compensation premium and doesn't have a good handle on controling costs, this might be a resource for you.
