Lobbying is considered the most popular and major method used by pressure groups because it involves direct interaction with legislators and policymakers to influence decisions before they become law. It can include sending letters, providing research data, making presentations, or face-to-face meetings with government officials.

While strikes are a powerful tool used by labour unions, they are a "method of last resort" when persuasion fails. Lobbying is the day-to-day, ongoing activity of most successful pressure groups.
