What aspects of the workplace might motivate people's acceptance of change?

An open and communicative environment is key. People need to be informed about what is going on and how the change will be helpful to them, and to clear up any miss givings that they might have about said change. They will need to understand that this is for the good of all the company and not just one or two people. If any training is involved, then the better prepared people are for the change. The better trained, they are and the more comfortable they feel before the change happens, will help ease the adjustment curve to the new system.
