Pensions are confusing for most people, which is why a lot of people never bother to look into it. Each organisaton will have its own pension scheme which you can opt into – as a young person, it is unlikely you will automatically be enrolled into this as you need to be either 22 years old or earn a certain amount of money. The Pension Advisory Service website has lots of information regarding pensions, but you can also ask someone from your place of work – usually the HR department or someone who is in the payroll department.
