The farmer needs needs you for his big push effort on haying on your day off when you made other plans. The farmer is not able to instruct you for a day or a week because of a child's illness, the tractor has broken down, or a business trip is necessary. You are asked to do backbreaking, tedious work for five days in a row, and asked to do it by yourself. Evaluate yourself on the reaction you feel to each of these situations. Talk to the farmer about how you think you would react if these situations arose.
Communication is key.
