As with all equipment in your facility, your workers are important parts of the operations process and the bottom line. Keeping them safe is always a high priority, but just as important is making sure they can be comfortable (or at least as comfortable as allowed) so that performance and productivity have less of a chance of faltering. You want to protect the human body from unnecessary strain and stress in all situations, but while standing is an area easy to offer help and reduce fatigue.
Applying the use of anti-fatigue mats throughout your facility can not only aid in this never-ending quest to protect workers but also enhance areas not thought of as important for continuous care.
