A good business prospers not just because of good sales, quality etc, but also through managing all aspects of its operations. If health and safety is at the forefront of its processes and culture any business will success against competitors who focus on sales alone.
Not only will your accident record be reduced, your absenteeism will be reduced, the quality of your employees will be increased, your product quality will be improved, but more importantly over time your reputation will grow.
By managing health and safety the generally unseen costs resulting from accident and ill health will be reduced and hopefully eliminated, i.e. the cost of absence through accidents, claims from injured persons, reduction of insurance costs and ultimately the avoidance of prosecutions and imprisonment following HSE enforcement action. All of which can drive a successful business to financial collapse through fines and poor public relations.
