The construction worker is from Toobworld, but Superman is from the Cineverse. At least this one is - there are at least four Supermen from different TV dimensions in Toobworld. There must be alternate dimensions in the Cineverse as well, considering Clark Kent/Kal-El has been portrayed previously by Kirk Alyn, Christopher Reeve, and Brandon Routh. But the Cineverse isn't my bailiwick, so I'll leave that to others to splain away.
But this is Henry Cavill's Superman from "Man Of Steel", so we have a Cineverse character in a Toobworld setting. So this blipvert (also used for Carl's Jr. depending on the market) takes place in the Borderlands where dimensions of Toobworld blend with the other fictional universes (like BookWorld, the Cineverse, the worlds of theater, song, and comic books, etc.)
The construction worker could probably be found in the main Toobworld, but whether he's a serlinguist there as well isn't known.
As for Superman? His Earth Prime-Time version was played by George Reeves in the 1950s. (That son of Krypton died in the early 1960s, according to Toobworld theory.)
The other televersions of Superman - man and boy - from other TV shows are in other TV dimensions. In fact, Tom Welling's Clark Kent is in 'The West Wing' dimension.
Up, up, and away!
