Not sure what “se” services are ? You hire out your services on an hourly basis. I know some planning from your customer, in this case RYR needs to be fulfilled for planning purposes. But surely if you’re self employed you dictate when, what and where you want to work. Or am I missing something. If you want an employee you hire somebody on a permanent basis with all that entails. I would even consider RYR if I could say that in the month of February I will be only working xyz days. Beggars can’t be choosers as they have become now.
