I'm curious to know if I'm being exploited with this ongoing freelance reporter job. The pay is £50 per event covered. The events can be around two hours long, and the final text averages 2,000-4,000 words. I'm told it should take no more than two hours after the event finishes to write up the summary, but it usually takes me about six hours, sometimes more. Am I being slow or am I being exploited?
