Next week, I am returning to the CDC for another 3 week conference during which I will be interpreting simultaneously. This is a difficult and a technical conference. I have worked at this conference twice in the past though so I am getting pretty familiar with the vocabulary.
When I got the call for the job, I was offered the same day rate as before. No surprise there, after all, why would they decide to increase the rate? But since the rate had not changed since my first time there (1 and a half years ago) and since I am getting comfortable with the vocabulary, I decided that an increase would be welcome.
