i think if you offer a guarantee its fine
unless you work for yourself and no staff and are happy to lose a day or so , what kind of business can keep knocking off work in the rain??
i only want to take 4 weeks off work a year for my own holidays any more for bad weather is cutting into my earnings , no thanks
but i am paying a wage which is ever increasing so its different now, i have stopped for the rain in the past when it didnt matter so much but now id rather have everything upto date no matter except for the most serious of bad weather...
