Teaching English as a microenterprise. I have one big customer (a school) and it seems possible they are going to want me to do additional work for them next year. Which would be ok, but I am worrying about if I can stay as a microenterprise (or if the authoritis are going to insist I should be employed by the school) if I do 15 or even 20 hours a week for the school, and just 2 or 3 hours for private customers. Is there a threshold does anyone know? Thanks
