The command structure may be there, but not the element of control.
An employee is free to resign if he would prefer to work for someone else. He can't be sent to a gulag. Customers aren't forced to accept a company's product or service, and can choose a competitor instead. Managers can fire incompetent or insubordinate workers. Customers can criticize a product without fear of being shot.
Customer, manager, employee, investor -- everyone is in the situation voluntarily, so they must negotiate on the basis of mutual self-interest. The company as an entity is more stable because its constituents aren't essentially at war with one another.
Unless the market conditions are such that workers cannot move from one place of employment to the other due to collusion between capitalists or if the economy is such that it's impossible to switch jobs.
Let's be honest, job mobility even in market economies is a difficult affair for everyone but highly qualified professionals. The fact that IT workers can get a new job in a month is not indicative of the economy at large.
