In one of my presentations, I ask the question, "What is the opposite of love?" One of the most common answers is, "Hate." While that is not wrong, I think the real opposite of love is "apathy." If love is caring about someone else the opposite is clearly the total lack of caring.
What makes apathy worse is when we are working around others there is an unconscious sense of security -- if I don't see a hazard then someone else will point it out to me. If I think they care and in fact, they don't, and I am left without that level of protection.
As safety professionals and team members, we know many injuries happen every day because someone saw an unsafe condition or behavior and failed to take action. Sometimes it makes you wonder if people actually care about others.
