A pressure group formed only by teachers is an occupational group. An occupational group is a pressure group that represents the interests of people who share a common profession or occupation. In this case, the group is made up solely of teachers and would therefore advocate for policies and changes that benefit teachers and their profession.
Occupational groups are one type of interest group, which are organizations that seek to influence public policy and promote their specific interests. Other types of interest groups include economic groups, which represent businesses and industries, and promotional groups, which advocate for particular causes or issues.
By organizing as an occupational group, teachers can leverage their collective influence to push for policies that benefit their profession, such as higher salaries, better working conditions, and increased funding for education. Through lobbying, public campaigns, and other forms of advocacy, occupational groups can play an important role in shaping public policy and promoting the interests of their members.
