The American Postal Worker Union plans to air three new TV ads nationally on the three major cable news channels — CNN, Fox News Channel and MSNBC — and occasionally on “NBC Nightly News.” The union hopes the messages might compel the U.S. Postal Service to scrap plans to start closing locations after mid-May to save tens of billions of dollars.

The first message stars several people that would be affected by closures — postal workers, small-business owners and elderly people who rely on mail deliveries of medication:

The second message stars Walt Gale, a 22-year veteran of the Colorado Springs mail-processing plant, who says the location is used to process more than 1 million pieces of mail daily — mostly bills and medicine.

The final message stars Michael Bazinet, who owns Creative Digital Imaging, a Bangor, Maine-based firm that relies on a nearby processing facility to quickly deliver shipments. Bazinet says he might have to lay off workers if his firm can no longer guarantee speedy mail deliveries.

What do you think of the ads? Do you think they’re effective? The comments section awaits your thoughts.
