Moldova- Social loafing refers to the tendency for people to avoid doing any work and let others do all the work instead.
An example where is often occurs is in the schools in which parents happen to volunteer. There are always volunteer opportunities in school and many parents sign up to help at various activities.
There are always the same parents who pitch in and do all of the work while some manage to arrive at the event late having done no prep work because the rest of the group took care of the details.
This type of parent wears on the other parents because they tend to take credit for work that they never did. This is a great example of social loafing in teams.
