The only union totally dedicated to people in Santander by being “Your Voice At Work”.

Your Voice At Work

Advance Union is a forward-thinking union offering professional advice and support to its members and collective lobbying on critical workplace matters. Since we were formed in 1977, we have become a robust voice, championing the things that matter to you at work. We believe there’s a right way to achieve results – and that’s through constructive relationships with employers and other unions. By keeping the lines of communication open, even when we disagree or can’t get what we want, we can find a way to make the situation better.

Why join Advance Union?

We represent and speak on behalf of members within Santander and its subsidiaries to improve your working life.
