I have hear many "stories" about for "per episode rate" here.
According with Greek labor law and unions that it doesn't exist.
It's only "per day" or "per week".
The actors/actresses it's different story.
Many "productions" here offer "per episode" rates and not "per day or per week".
Be careful my friends because here we are "laboratory animals" for the "future labor and how it paid".
In one episode you can work for 4 days.
In other episode you can work for 10 days.
It's not the same for rates this.
So be careful.
