"Corporate values" initiative to get employees to vote (hopefully democratic)
Almost all corporate HR departments have a "corporate values" initiatives. These are created to get employees to feel good about their company's meeting social responsibilities. I suggest a liberally minded non-profit could develop a campaign to persuade companies to include employee voting in all local and national elections as an area social responsibility. We could even supply the HR department with data if their employees voted, of course NOT including who they voted for. I would note that some HR departments may score their employees on their corporate values goals. This can even impact an employee's bonus. So HR could bake this voting data into an employee's score.
The non-profit would provide branded marketing material to the HR departments. They would need to have a booth at HR conventions etc and advertise in HR trade rags.
This campaign could target companies with desired demographics for liberal voting.
