After reviewing the bids for August 2011, I found some potential fatigue issues regarding recent schedules for EWR Flight attendants. I am requesting the scheduling department take notice and am advising them not to allow these schedules to continue. As we are at risk for fatigue. NO 4 in a row day trips NO NMB more then 1x per trip NO more then 5 legs per day per trip and especially on our "Friday" NO less then 12 hour layover,unless its a stand up
