Many union staff help students more than anyone can even thank for. Just a simple awards ceremony for those who have gone above and beyond would go someway to helping that!
Personally, I've been helped so much by the Student Engagement Officer and the Advice centre so much this year. I know Societies could not function without the Societies coordinator, and nobody could function without the hard work of the finance office.
It's unfair that none of these people ever get the credit they deserve!
