Bureau of Meteorology staff have hijacked the weather bureau’s website and media appearances to step up their campaign in protracted pay negotiations after a five-year pay freeze.

In online weather forecasts across Australia this week, staff wrote the message, “Bureau staff have been fighting for years to hold on to the conditions we have, but they are under attack.”

This action follows a series of smaller acts of subversion by Bureau of Meteorology staff to draw attention to their social media campaign by integrating #5yearpayfreeze and #BOMonStrike into online forecasts.
