A work colleague chose to visit a sick relative, at their home (breaking our Tier 2 rules, I believe). Some people might say that is their business/choice. Unfortunately, said colleague went on to catch Covid from their relative (who has, sadly, since died from it) and my place of work had to close while members of staff got tests to see if they had been infected. Fortunately, thanks to masks/sanitizing/distancing, the rest of us seem to have got away with it. But it has been a scary time, and we've all suffered financially as a result of this person's actions. I don't even know how I will be able to look them in the eye when we return to work, I am so angry with them for putting the rest of us at risk. Also sad for the loss of their relative, of course. A mix of emotions!
