It is like when my employer sponsored "Learning and Development Week" which had a stated goal of fostering a culture of continuous learning. They planned to make this an annual event. The conflict in event design and stated goal was too silly to even attempt to address.
Each day I learn and practice my craft. I evolve with business. I don't need a dedicated event to tell me to grow. It's a natural process; just look around the org and you can see it. No event needed.
And the "forced march to event-based training" as much as we want to believe has some good side-effects (heighten awareness, etc...), I would hope that L&D leaders would educate sponsors on good principles (spacing effect, embedding learning in the workflow, etc.) in lieu of participating in reinforcing "Learning Day, Week, etc..." It sells out our craft and reinforces perceptions that need no more fuel added to its fire.
