As a manager, you can expect compliance when you institute mandated changes in a work place. However, mere compliance is not typically enough in most work situations. Therefore, it is important to get employees to buy into the changes as much as possible.
As a manager, you have legitimate authority and employees will obey your orders or be disciplined and even fired. However, workers who are angry and upset will easily find ways to become less productive even if they are not being openly defiant. They might not even consciously try to be less productive, but will be demoralized and therefore not work as well.
For these reasons, it is very important to get workers to understand, and hopefully to agree with, the changes that are being made in the workplace. Ideally, they would be included in the process of planning the changes. At the very least, they should have the changes explained to them with emphasis on why certain changes are being made.
Thus, you can expect compliance with your orders since you are the manager. However, if your workers are just complying, rather than working their best, your firm will suffer.
