SHERMAN, TX - President Obama returned to the White House Wednesday after a costly and bruising campaign to win a second term. Emotions are still running high among voters and one of the outlets people are using to express themselves is social media.

As soon as the president was re-elected, millions logged onto Facebook and Twitter to voice their opinions. I spoke with a career counselor and business owners about the repercussions of discussing politics in the workplace.

Markl and Sons Cooling and Heating owner John Markl was posting his political views on Facebook since before the election. He not only posts his views, he wants his employees to voice their opinions too.

"Not only do I allow it, I encourage it. I think it's important for people to understand the political world and what's going on in the political world and how it relates to the workplace and your job and your future employment," he said.

Workforce Solutions Texoma's Bob Rhoden said discussing something personal like politics and religion can cause tension in the office, which can also affect productivity.

"Bad feelings start, people don't want to work with one another then all of a sudden productivity does start to go down because that good attitude that you have, that you need to bring to work in order to be as productive as possible starts to slip away," he said.

Rhoden also said it's important to watch what you post on an open forum like Facebook because controversial posts could not only cost you friends, they could cost you business.

"You never know when your employer may be looking around on Facebook to see what you've posted and maybe on Twitter, LinkedIn or somewhere else you may have posted. But remember, once you put it on the internet, it's not private anymore," he said.

"I suppose that you could potentially lose business over it but you can also gain some so I really consider it a wash over the years," said Markl.

Another business owner, Bruce Maxwell said he didn't think he lost clients by posting his political views on Facebook.

"Not that I know of, but I don't think people would necessarily tell me why they're not ordering from me or that they're unfriending me or something along those lines," he said.
