Shareholders and the Board appoint people (aka management) to run a company. Management has a fiduciary duty to do what is optimal for shareholders (maximimize value). If your company will help management do that, they may choose to work with you. Owning shares has no direct influence as far as I can tell. Of course, owning a lot of the company might give you a voice they'll listen to.
