The output of top and powertop would be helpful.

kworker? No such package exists in either the official repos nor the aur.

Figured it out.
The issue was limited to a single user account. I was playing around with gnome activity journal this morning and I removed it before I ran a system update.
It appears however that running pacman -R did not remove the lot and the zeitgeist folder in .local remained along with a few startup scripts. Deleting the lot fixed the issue.

@SS4 - kworker is not a package it is is a placeholder process for kernel worker threads.
