"No work will have as much happiness as it ought to have, or will be as well done as it should be, until fellow-workers exchange experiences and advice with one another." Every girl can learn something about her work from others in the same occupation. To learn from a friendly fellow-worker is pleasant and easy compared with the difficulty that we find in learning from people who are not specially interested in showing us how to work. Some of the happiest groups of workers are those who have organized to promote friendship and good feeling amongst girls and women who are in the same occupation. This is what the girls of one such group say of the benefit of belonging to a friendly social organization of which the members are fellow-workers: "It improves our work, because we know how the others do theirs and we want to do as well as they do. We talk over problems in our work, and hearing the various ideas and solutions that others have thought out helps us in solving our problems. We do not meet to discuss our work primarily; as a rule our gatherings are for enjoyment and recreation. But work every now and then comes into general conversation and in this way we learn. It is a help to have for a friend one of the best workers in your occupation. You try your best to keep up with her. If any of the girls needs a new position, or is in difficulty about her work, she may talk it over with one of the older workers. In the same way we advise one another about wages. We can find out what is the average wage and the best wage paid in the occupation and what are the average hours of employment. Many girls in the club have found new positions and have been able to ask for and get higher wages through the advice and help of other club members." Every girl knows what a help it is to work with others when sewing, mending, dressmaking and trimming hats. The girl in paid employment finds this work more trying than the girl who remains at home, because the girl at home generally has spare hours during the day when she may do work of this character. A mending circle meeting once a week could plan some entertainment to accompany work. One of the circle might read aloud, or all the members might take turns in telling a story and adding in some way to the evening's entertainment. Girls in such a circle could all help in blouse making or in millinery. One or more of the members might have a special gift in cutting and fitting. Others might be more skilful in sewing. One or more of the girls might have a special gift in buying. The possibilities of co-operative work of this kind for girls in the twentieth century are very great indeed.
