Good day, Please could someone help me. I'm in a position where my employer has not automatically enrolled me into a pension even though i meet the criteria and has now said they would start with the pension contributions form the 1 March 2024. If we were to backpay the last year missed, am I also obliged to backpay my amount or can the employer backpay and I continue as normal from the 2 March? Many thanks x
