For UPS driver and Teamsters member Britt Miller, that future includes Facebook.
"There's no direction manual on this yet, so everyone is making it up as they go along," said Miller, who manages the Facebook page for Local 222. It has about 520 likes so far, but he said most union outreach still happens in person.
"Face to face is where … you can ask questions, answer questions and address concerns," he said. Though Utah has a relatively low number of organized workers the percentages have slipped from 6.2 percent to 5.2 percent in about a decade they said Monday that membership gives them security in wages, benefits and employment.
"I wouldn't have a little one like this without the union," said Mike McDonald, who wore a white cowboy hat and checkered shirt as he held his 10-month-old grandson, Jace, on this lap.
"We're not rich, but we have a living wage" that helped pay for things like hockey for their children, said his wife, Sandra McDonald.
The business manager and former president of Ironworkers Local 27, Mike McDonald is the son of a union worker and counts more members among his children and grandchildren, including 23-year-old namesake Michael McDonald, an apprentice with the International Brotherhood of Electrical Workers who joined a year ago.
"As long as you're working hard, you'll have a job," said the younger McDonald, who has worked on data centers for Xactware, eBay and Beehive Data. "It's something to work toward you'll have a lifetime skill."
For others, though, all that was far in the future. Three-year-old Tristan Harding, whose grandfather is a union electrician, was just excited to slide down a giant inflatable shark.
"As we were driving up, he just said, 'Oh, I want to go on the shark,' " said his mother, Mindy Harding of West Valley City. While she knows that her father's union has helped him find work during recent lean times, for her children, Labor Day picnics are also about fish ponds, firetrucks and memories.
