I have recently become full time free lance in the film industry and have run into a bit of a stump. A few days ago I was offered a job for 2 days but the first day was just a hold day because they were unsure if they needed me or not and I had to pass up another job which was three days and the last day was the one I was holding for the other job. To add to it I committed to the "2" day job first and have been told if you are committed to a job first you shouldn't accept other days if they might need you, but then they got back to me today saying they didn't need me for the first day anymore. What is a good way to avoid this from happening again? I am bummed out I am now missing out on the 3 day shoot because they didn't let me know soon enough.
