Conservatives don't generally project their worldview through the lens of large social groups pitted against each other, so it's kind of meaningless to argue about whether conservatives are pro- or anti- working class. They aren't generally pro- or anti- any "class" from their own perspective, because they don't think dividing society up like that is a legitimate thing to do to begin with. A typical conservative would say something like: what do you call the boss of a small window cleaning firm? Is he a capitalist or a member of the working class? The left generally ignore questions like this because they can't answer them. But they do spend lots of time trying to tell everyone that society is simple and "conservatives" are one big blob that all hate "workers". Generally conservatives are anti-union, because historically unions have been very tied up with communism, very aggressive/violent and very anti-competitive, all of which are antithetical to what libertarian conservatives believe yield the most socially beneficial outcomes. That is, they're anti union because they think unions are in fact worse for the "working classes" - to the extent such a concept makes sense at all - than not having them.
