I think people are going slightly off track with this one OP and making it a 'ooo you think you are so important' thread
so can I just clarify....
-
you run your own small business so it's pretty important that you are there, especially on a day when staff will potentially not arrive at work
-
your wife works in a public sector job with the flexibility to take time off that most private sector workers would give their back teeth for
-
together, you made the decision that she would take the day off to look after dd -you didn't make her
that is one issue taken care of -YANBU
the other issue, as I understand it is that as an employer running a small business, you are concerned about taking on female members of staff due to their potential to take time off to look after dcs etc, and the fact that your wife's day was disrupted today due to the weather, made you think about it and post the question on here today?
there are massive financial pressures on small business in relation to materity, sick pay, upcoming changes to pensions, NI etc etc
and yes if you have you only have 5 staff and 2 off them don't show up it can have a massive impact on the running of the business and as the owner, this is obviously important to you -as it should be
as other posters have pointed out, men as well as women can have time off uexpectedly at an actual cost to the business and also as a knock on effect to the business
as a manager, my personal experience is that it is the mothers that take time off I had to today and for everyone saying 'why is the father's job more important, he should take time off' -society is not going to change overnight and that is the reality, especially if one parent works part time and the other full time, it will usually be the part time person that takes the time off in my experience
I do however employ a man who's wife is a nurse and it is him that takes time off, and I have a single dad who works part time and will take the time off if needed
YWBU not to employ a woman on the basis that she would possibly have more time off, but I do understand why you would be concerned about it so YWNBU to worry about it
