Zombie Penguin managed to sabotage the aerial spraying and slowly the events of the 1886 Haymarket affair are coming back to collective memory. But Antarctic Oil will not let this happen so easily. The Board of Directors has established a plan to re-enslave the minds of workers and make them forget once and for all the eight hour work day. *May 1 was chosen to be International Workers' Day in order to commemorate the May 4, 1886 Haymarket affair in Chicago. The police were trying to disperse a public assembly during a general strike for the eight-hour workday, when an unidentified person threw a bomb at the police. The police responded by firing on the workers, killing four demonstrators.
