This issue, I find, is the biggest problem of the Internet. Once you get used to checking the news all the time, you will find that during work time you are distracted from the business/work at hand. Instead of looking at /creating your to-do list or delegating tasks, you are constantly checking the news.
The best way to handle this is to subscribe to new alerts/digests so you will be informed, but don’t need to be emotionally tied to the news. If there is a real business need to know about social media happenings, you can subscribe to services like Twilert, which let you set up custom instant notices that let you know what you need to know. Make specific times when you check the news, and the rest let the automated systems give you the news you need.
It’s a different life when you free yourself from this.
Hatzlocha!
