Workaday code should be documented so another developer can skim it in n minutes rather than spend n3 close-reading it.
If workaday code needs documentation for other developers to understand it to begin with, it needs a rewrite. Even if it runs great as code, people aren't computers and it needs to communicate it's purpose to both. Finding a showstopping bug under pressure in code like that is enough to make you want to put pencils though your eyes.
Others also seem confused— it clearly wasn't the best wording. Maybe the usage is more common in my regional dialect or something.
'Workaday' technically has two definitions: the first is something work related, and the second is something ordinary, common, or routine. Both definitions carry connotations of the other though. In this context, I'm referring to the everyday code that we write to solve most problems. I'd juxtapose this with unusual code working around really weird constraints or making up for a fundamental shortcoming or bug in a language or critical library which might require janky counterintuitive code.
