I don’t think me taking the same training 5 years in a row shows any more compliance than me taking it once.
It’s extra effort to figure out who has taken it or not so they just have everyone take it.
I expect that in time, BS courses that show nominal compliance will be shown to be part of a workplace culture of not caring. But I shudder to think what the next form of compliance will be and will likely be much worse than watching a video once a year.
