Leadership
Employee communication is as much to do with influencing others within the organization to get objectives achieved as it is to do with actually implementing communication plans.
Communicators should demonstrate leadership in their roles.
This meaning isn't to do with whether you have 'manager' or some other other word in your job title. It's all to do with the confidence and passion for achieving your objectives you need to project in your relationships with others you work with.
With confidence and passion, you can achieve almost anything.
