A person with a compulsion to demonstrate "presenteeism" by travelling to the office via any possible means during heavy snowfalls, when home working is a readily available alternative.
Rosa - Transport system and schools closed down by several feet of snow, but good old Simon made it into the office yesterday I hear.
Emma - Yes he told anyone who would listen about his epic journey to work on cross-country skis.
Rosa: But he only had to do a bit of non-urgent filing.
Emma: Yes I know, he's such a snow martyr.
