I assume they do the self study and it takes less time than the hours credited. That is how my CE was and to be honest, it was a complete waste of effort and worthless, but checked the CE box with no value added to my employer for paying for it. People are pissed because they actually have to work the six hours they are paid for something the leaders feel is important?
Maybe it's just me, but the attitude seems very entitled. Not abnormal with employees these days...
