If you want to come into work for some reason, you can, but you have to have tested negative beforehand. I used to go to the main campus for my covid tests, but the main hall they had turned into a test centre has now been turned back into the University's main hall. That is not a problem, though; you can now just pick up a box of self-tests from a variety of locations on campus, and just test yourself at home. Much more convenient! So when I was in Bangor anyway, I popped by the reception of Main Arts, and picked up a box. I will be wanting to go into the lab some times. I can I just prepare for that at home!
