Slackware :: Should Glibc Be Updated In Current Every Time There Is Kernel Update?

I am running Slackware64-current(multi-lib) and I have stumbled across something that I don't fully understand.I have read that the kernel-headers should not be updated as glibc is compiled against them and therefore requires that set of kernel headers. Recently the kernel version has been bumped a couple of times but glibc has stayed the same.Should glibc be re-compiled each time there is a kernel update?

Perhaps someone can explain, in very simple terms, the relationship between the kernel, the kernel headers, the kernel modules and glibc.
