Why did 150,000 public sector workers go on strike in the North

Official figures show that between April 2022 and April 2023, real pay (adjusted for inflation) in the public sector fell by 7.2%. That decline came on the heels of real pay falling by more than 4% between April 2021 and April 2022, and two decades of no growth in public sector real pay. While there is much talk about an “Irish Sea border” because of post-Brexit trade arrangements, a sea border of sorts already exists when it comes to public sector earnings. Differences in public sector pay between the North and the UK are substantial and even greater over the border in the rest of the country. Newly qualified teachers in Britain make about £30,000, while in the North they start on £24,000 in the south they start on £33,375. A newly qualified doctor in the North earns a base salary of £26,000 per year.
In England the starting rate is over £32,000

In Scotland it is £31,000.

However South of the border a newly qualified doctor starts off at £52,986.53 per year in the HSE twice that of a doctor in the North
There were calls for Pay parity with “The rest of the UK” People and unions need to decolonise their minds forget about Britain and turn their attention to building a united Ireland as envisaged in the 1916 Revolution.
