It can be a thin line between our personal and professional lives, and this is something a lady bus driver learned the hard way recently.

The school bus driver in Princeton City, Ohio was reportedly fired immediately after concerned parents saw her post a questionable photo on her Facebook account, Fox 19 reported.

The photo appeared to show the bus driver behind the wheel, with her lips around a bottle of beer. When parents and officials from the Princeton District School saw the photo, they were outraged.

Her employer First Student Transportation immediately took action and reviewed the case.  It deemed her actions unfit for their services.

In a statement, the company said that they do not approve of their bus driver's drinking selfie. "We understand and share in the concern this photo has caused the Princeton community. As soon as we became aware of the photo, we immediately began an internal review of the matter. We are incredibly disappointed by our driver's actions," it said.

Their investigation revealed that the bottle cap was still on when the selfie was taken, thus proving that the bus driver was not drinking on the job. She was also off-duty at the time, and no students were onboard the bus.

Still, her actions were frowned upon by the employer, who decided to terminate her services. "We are incredibly disappointed by our driver's actions. Behaviour such as this does not align with company policy and the high standards First Student strives for in all we do," it added.

Fox 19 also managed to obtain a statement from one of the angry parents, Sadie Leporati, who said the bus driver was very unprofessional and should not be allowed to drive for their children again.

"She doesn't care. She obviously doesn't care about her job," she said. "She shouldn't go back.  She should absolutely get fired. It was very inappropriate and very poor judgement on her part."
