If yo have to clean anything else then your server-room....run! Sorry that's not normal, there are cleaning institutes for electrical equipment...even in Birmingham.
Non-trained personal cleaning around electronics can be a source of IT issues. Unplugging things so they can vacuum or wax, dislodging cables with aggressive dusting, etc.
I'd rather be responsible for regular cleaning and maintence than get a call from the owner that the fancy electronic sign they overpaid for is down again because of a loose connection.
I've worked jobs like this, they were usually pretty chill actually. The actual IT work is pretty minimal (that's why there is only one of you!) so you don't really mind helping out with random tasks. This is a small[0] non-IT business, they don't need someone who builds k8s for funsies.
Honestly, it's beginning to sound like a lot of people here just think IT is a very narrow field that only encompasses people too aloof to wipe down a monitor on occasion or assist the receptionist in running a malware scanner.
This looks like the outgoing “IT manager” wrote up a list of their duties, then it got handed off to HR who thought it was a list of applicant requirements.
I really wish it had "unpaid internship - with a chance to progress to full time role for impressive candidates" (with free haircuts as a perk?)
Is it the The worst IT manager role I have ever seen if the pay is 7 figures? Is it the The worst IT manager role I have ever seen if the pay is 5 figures? Beauty is in the eye of the paycheque.
