The best I can do in situations like that is try to take the longer view; it doesn't snow most days so I look at those instead of the few days I have a problem. When the neighbors' dogs dump in my yard, I often just clean it up; it only happens maybe 2-3 times a year? I downgrade it from WWIII to annoyance.

Maybe you can "catch" the guys contractor and go stand on your property shaking your head one of the times it snows? It could be the contractor's doing, the owner of the property isn't the one doing the literal plowing, he could have just told the contractor not to hurt his landscaping; it's he and the contractor's problem, both and if you can get in the way of the contractor, take down the company name, etc. and call and complain, give them a hard time; they're not going to want to lose customers/service because you raise a stink?
