People in an organization have some continuing bond. This
bond, of course, does not mean lifelong membership. On the contrary,
organizations face constant change in their memberships,
although while they are members, the people in an organization
participate with some degree of regularity. For a salesperson at
Sears Roebuck, that may require being at work eight hours a day,
five days a week. At the other extreme, someone functioning on a
relatively continuous basis as a member of the National Organization
for Women may attend only a few meetings a year or merely
pay the annual dues.
