Just about all the Usual Suspects agree: Sunday, April 28 will be Workers' Memorial Day, a day to honor and mourn those who have died in workplace accidents -- and to call public attention to the continuing need for safer working conditions. The linked site says that worldwide, each year, two million people die from work-related accidents and disease. The site continues, "Worldwide, one worker dies every 15 seconds and in the U.S., 14 workers die every day due to preventable incidents."
Wikipedia says that Workers' Memorial Day has been observed in the United States since 1989.
Sunday will also be National Blueberry Pie Day and Kiss Your Mate Day. It will also be Astronomy Day, so spend some time looking up at the sky Sunday night -- unless you're at work, of course. If you're at work, keep yours eyes on the tasks before you. Don't get hurt!
