Operators have to work fast and carefully because they are paid the regular going rate for work done correctly. They are paid minimum wage when fixing pieces that weren't done correctly. While many shops are in old uncomfortable buildings, others are in modern buildings that have big workrooms, good ventilation and lighting, and air conditioning. Most employees sit when they sew, but the work can be tiring depending on the weight of the fabric and depending on what they are making. The work is done fast and many chores are boring.
Operators work alone, but very near fellow workers.
The material to be sewn is brought to them and put in baskets or separate piles so each piece can be reached while sitting at the machine. This process makes for smooth and efficient operations. Operators have to do some lifting. The machines are worked by foot pedals and knee levers. Certain kinds of foot and leg ailments are not a handicap for this work.
