I’m an Ea for our SLT. I volunteered a couple of years ago to be ‘milk monitor’, as in taking their £5/month and buying the milk, tea, coffee and biccies for the 9 of us. No issues so far. I nip to Asda twice a week on the way to work. I get the bus btw and all the money goes via a dedicated tea fund Revolut.
Now a fairly new member of SLT, has asked the other departments (over 100 people) if they want to join to save on the multiple milk situation in the fridge, and asked me to organise this. So I’d have to organise a regular delivery and payment AND be responsible for chasing every single person for their money!
I'm not a purchasing clerk, or what they’re called. I do this for our team voluntarily.
How do I politely say that sorry, but it’s beyond my remit!
