What led to the Noida workers’ protest?

The story so far:

The Noida workers’ protest, which escalated into widespread violence on April 13, has become a significant crisis for the Uttar Pradesh government. The unrest, primarily driven by demands for higher wages and improved working conditions, paralysed parts of the city’s industrial zones and triggered a massive security response. On April 14, domestic workers in high-rise buildings such as Cleo County also began protesting for higher pay. The administration took a dual approach of crackdowns and concessions. In a direct response to the unrest, the Uttar Pradesh government announced a 20-21% increase in minimum wages, effective retroactively from April 1. As Uttar Pradesh heads towards the election, the situation has given the Opposition an issue to corner the government on.
