The owner of my company has another business, both companies are very small and both share the same office space.
My problem is this, there's a senior employee working for the other company who seems to be trying to take the credits of the work I'm doing, I'm the company manager. He does this despite the fact that he's never contributed for this particular project.
He sits in the same area with my company, he's older than me and he's friends with the company owner. I've been in this project since the start and I know the ins and outs of the project and company so I know he hasn't been involved in anything.
Here's the problem, he listens to what I say to my team and gives his opinion to the company owner without really knowing the whole story or talking to me.
He askes the owner to add him to all of my company's software programs, all the private company documents, all the google analytics, social media back-offices, he requests to be on it all offering to help me with strategy and planning(I never asked for help). He never does share his ideas or opinions with me, he's just there so he can find flaws and communicate them to my company's owner. What should I do? Should I tell the company owner what's really happening at the risk of having them both turn on me?
I can see he manipulates my manager many times and that some of the feedback I have from the projects I do or are planning to do are deeply discussed between both.
This relationship both have is starting to affect my work and limit what I can do since he vets some of the things I'm planning to do. The company has been growing since I took the helm so I don't know what to do to explain to my boss how he shouldn't listen to the other guy. HELP!
