I too have some sympathies, OG. I have seen organisations where staff were quite happy working hard for the common good and then organisational changes meant new leadership teams came in, often supported by management consultants. who wanted to be seen to be changing things to show it was a new era and a new sheriff was in town. Some consultants make a fortune from 'culture change programmes'. Staff who used to be happy getting on with the job suddenly found they were expected to have fancy dress days, go canoeing after work and paint a community centre during working hours (and then have to catch up on the backlog of work).
But I do believe that overt resistance is a waste of time. I had to choose whether to change, smile and play along, or look for a company where I would feel more comfortable.
