I've recently accepted a position as marketing director for a local company. The previous director signed a media contract in December 2012 for 2013. She then left the job on 1/4/13. Upon my evaluation, this media contract is not in the best interest of my company and I would like to end it. Is it still binding even though it was signed by a director that no longer legally represents the company and only did for the first four days of the contractual time period?
