Sorry, but from my own personal experience there are people who do wander around the place sneezing and dripping snot. They're either the kind who like to boast that they've never had a day off in their lives due to sickness but fail to take into account the impact they have on the people around them, or they're people who are more susceptible to such illnesses and are terrified of calling in sick because of disciplinary repercussions. I've lost count of the number of times when I've been sitting next to a colleague that should really have been in bed, but they soldier on regardless because one more incident of absence will lead them down the path to a warning. This, coupled with the fact that sick pay is often only paid out after a few days of illness, leads people who really ought to be recuperating back to the workplace prematurely.Obviously those people who get more severe symptoms than average with a cold should stay at home. But that's because they are unfit to work. But what's being suggested here is that anyone suffering from a cold has a duty to others to remain at home. Quite frankly that is preposterous. The vast majority of people who suffer from a cold are not unfit to work or go shopping and they do not need to remain at home. They don't, in my experience go "wandering around the place sneezing and dripping snot." The majority of them try to keep their infections to themselves but it is simply not possible to do so entirely. The vast majority of people who might catch that cold will not be so ill that they will be unfit to work or go shopping or need to remain at home. It is completely unreasonable to expect someone who is suffering from a relatively minor ailment to isolate themselves from everybody else. It's unfortunate that some people suffer more from colds than others. It's also unfortunate that it is they who will have to keep themselves safe and not rely on everybody else to do it for them. I despair at some of the views in this country that everybody must be protected from everything - even down to a common cold. It cannot happen and the sooner that is accepted the sooner we can move on from this ridiculous state of affairs.
I've been in the position where I've wanted to send a member of staff home because they were utterly miserable with cold/flu symptoms and completely useless as a result, but because they'd had a similar occurrence of illness not that long ago, they were terrified that it would lead to them being dismissed.
