If this company is considered to be “one of the best in the world” then I don’t see why they wouldn’t want to go over safety procedures over and over and over. Lots of things happen in personnel during a companies history. People come and go. Also people get laxed, as they do in a lot of businesses, there wouldn’t be anything wrong with going over it again. After all, it is their employees lives and their livelihood.

I’ve been at my job for a number of years and occasionally I find myself forgetting skills,pediatric drug dosages,location of streets,etc because they are things/places I don’t use a lot so I have to pull out my cell phone and apps to refresh my memory. IP might only get one chance to get it right and not knowing it now might cost lives not just at the company but in the community. I’m not sure why the first comment got under your skin but I’d say, no! We aren’t joking! It pays to be overly cautious.
