How to get inverse object relation when specified related_name

I have the following model similiar to the relationship in the django docs https://docs.djangoproject.com/en/1.11/ref/models/relations/:

class Employee(models.Model):  
    user = models.OneToOneField(User, blank=True, null=True)  
    company = models.ForeignKey('companies.Company', related_name='company', blank=True, null=True)
    brand = models.OneToOneField('companies.Brand', related_name='brand', blank=True, null=True)

I try to get the employee from the Brand like this:

attendees = Brand.objects.filter(pk=2)

for a in attendees:
    print a.employee

I get the error:

'Brand' object has no attribute 'employee'

I have also tried:

attendees = Brand.objects.filter(pk=2)

for a in attendees:
    print a.employee_set

and get:

'Brand' object has no attribute 'employee_set'

How can I get the employee from the brand?

Thanks

The problem was related name:

brand = models.OneToOneField('companies.Brand', related_name='brand')

I changed it to:

brand = models.OneToOneField('companies.Brand', related_name='employee')
