Richard.. In the UK it is known as "Throwing a Sickie"....usually reserved for the sort of day when you are unable to face some event at work, or just can't be bothered to show up...S**T Happens, said the bumper sticker., looks to be true.
My son is an Architect... he says anything that extends the job is welcome......so look on the bright side, just blame your internet provider.
