Ha. Do you mean that anyone in the company (including top management) should embrace criticism from anyone else in the company (including the employees)? Or do you mean only that the workers should embrace criticism from their bosses?
If the former, then top management should provide live examples of themselves changing their mind based on feedback received from employees. Only then will the employees believe that management means it about creating a culture where people embrace criticism.
If the acceptance of criticism is only intended to go in one direction, from top to bottom, then simply use the standard management tools of reward and punishment.
