Do you work with a specific community or organization, or just take opportunities as they come up?
What type of volunteer work do you like to do? Do you like the stuff where you are just a warm body - someone to hold a sign or greet people? Or more involved tasks that are more like professional work? What about shudders door knocking?
I used to do that at my previous job and used to chuck it up to being good for the business if the boss asked, but in reality, I just liked seeing the street clean while getting paid for it.
Similarly, I use company equipment to pick up the larger amounts of trash or furniture items.
A commercial vehicle backed into a ditch has had the side effect of attracting a few police from time to time, but it’s never been any trouble. No clue if it helps the business in terms of image, but it sure helps me feel better.
