Let go of the past

Often in institutions we have "the way we’ve always done it".

I don’t like hearing it, but I assume people who use the age-old chestnut don’t like hearing "let’s do something different".
I think that one of the most passively-aggressive response to doing something a different way is to be involved in the new model, but then change one thing at a time so it overcomes all of the advantages of the new model, which serves to make it a shiny new version of the old model.

Then, you can proclaim proudly, "See, I told you it didn’t work." Then, you can go back to doing it the old way.
