Avoiding container lines in dependency injection in symfony

New for symfony and php. I was able to successfully define the service and inject the doctrine entity manager into it. It works fine, but during initialization, I have to pass a string containing the service name like this:

    $eRep = $this->container->get('employee_repository');

      

        
        
        
      

    

Can this be avoided? Could this be converted to something more elegant like

   $eRep = $this->container->getEmployeeRepository();

      

        
        
        
      

    

The service is defined as:

services:
employee_repository:
    class: AppBundle\Repository\EmployeeRepository
    arguments: [@doctrine.orm.entity_manager]               

      

        
        
        
      

    

Sorry for the question about the nob. EDIT

Can I access the service container inside another class, say EmployeeEnvelope, and call the following:

class EmployeeEnvelope{

    public function getEmployeeRepository()
    {               
        return $this->container->get('employee_repository');
    } 
}
