Why would you even want to work in this weather anyway, desperation? Your clothes would be wet through, transfering onto your van seats, everything steamed up in the van, cold, miserable,dangerous,customers pi..ed off with you turning up,( even if they dont tell you to your face)The list is extensive.
I have priced my work well to factor in days when i cant work, and just do a bit extra when the weather is good.
I expect the decision to work or not is tougher if you employ staff who are keen to work and are on contracts?
