"What an extraordinary day. Over 50,000 teachers, rail workers and bus drivers stood up to the Government, went on strike and demanded a better working life. This is people using their collective power to put their working life and destiny in their own hands," local unions tweeted.
According to a follow-up tweet, the demonstration called on the state government to address such issues as "job security, overwork, unpaid overtime and stagnant wages."
According to the 9News media outlet, educators urged the government to raise their wages by 7.5% a year, as well as reverse staff cuts while the state lacks over 3,000 teaching positions, causing increased workloads for remaining workers.
Rail employees and bus drivers demanded their salaries be raised by at least 2.5%, the outlet said.
The major strike caused disruptions in transport traffic and the closure of around 400 schools across New South Wales.
