Something that has helped me to move up in my career at HMRC is taking on new tasks from working on additional projects for the HO's in Customs to training new starters to the business. I actually wrote and delivered a training package for new starters when I was AO in Customs, I felt this not only increased my skillset but it also helped me to make sure that anyone starting in the same role as me learnt the job from the perspective of an AO. I have also taken on projects where I have led a group of people, for example, clearing an email inbox where we had a large number of emails. I delegated colleagues to cover particular time slots, making sure that the emails that had been waiting the longest for a response were dealt with first.

You will bring a unique perspective to a role as your experience will have been different from that of others. Don't be afraid to bring that to the fore, it is what makes you, you and brings a valuable contribution to a team. I wish I'd thought this more when I first joined the Civil Service!

I've had a huge variety of roles in HMRC, and I've enjoyed all of them. I've found it's not always necessary to chase promotion. A sideways move to another area can expand your horizons and build your skills and this is recognised when you're ready to take the next step. I've always tried to maintain job satisfaction above all else. I've done a couple of jobs I've really hated, so I moved on and found something else. I've found if I'm happy in my job, I perform better and this is noticed. Also, don't be afraid to ask for opportunities or for what you want. I've always believed 'if you don't ask, you don't get' – the worst that could happen is someone says no and you're no worse off.
