Understand the power social media has in our society is critical and even more so for businesses. You can either be in front of it and use it to your advantage or wait until the shoe drops and pick up the pieces.
Employees are the face of and represent your company, how do you want them to do that? Do you want a united front or shooting in the dark and hope it hits the right target.
Control social media or it will control you, in a sense. Determine your needs, put a policy in place, and use it for positive growth, online branding, keeping up with your customers and vendors, and stay ahead of your competition.
