Communication pressures cause many trials and tribulations for those who stutter. Students should ask that they be allowed to recite first or close to the first as they are more likely to stutter if they must wait behind half the class for their turn. They should also let their teacher know that they have good days and worse days and that is why they participate in class one day and not the next.
Stutterers who are in the workforce should do the same thing with their employers and coworkers. It is better to tell them upfront that you stutter and that certain things help you or hinder you. You will be accepted better as part of the team if you talk with them about your speech and let them know how they can help you.
