One of the joys of working in an air-conditioned office is that you often get to experience four seasons in a day. I will admit that those seasons with a recognised equinox do pose more of a challenge. Sure, you can come to work armed with a bag of autumnal leaves and a flask of spring rain to help things along but generally Winter and Summer tend to hold sway.
There’s a theory that’s half fact half urban legend that you are legally obliged to be sent home from work if temperatures fall outside certain parameters within the workplace. Lower than 13 degrees or above 30 degrees Celsius seems to be the accepted rumour for the UK. Aussies are much tougher and only start having breaks in their day when it hits 35 but even there it’s apparently hometime when it hits 38. The lower band is unlikely to be problematic down under.
