I dunno man I worked on a landscaping truck and on a pumping truck for the parks department when I was younger and we had plenty of free time to dick around. This was before smartphones so usually we'd play Hearts at the truck dispatch or park at one of the town beaches and just watch the water and read magazines or books. Walk past any roadside construction site and half the guys are playing with their phones; anything with cops standing around half of them are playing with their phones. Not sure how to tell you this, but blue collar jobs have downtime same as white collar jobs and they have the internet on phones now.
