As equipment libraries are becoming more popular. What is the typical grading nationally of a library manager's post? confused

I have responsibility for a large amount of 'common user' items of equipment, typically, volumetric and syringe pumps, monitoring equipment, feeding pumps, nebulisers, blood warmers etc and Pegasus beds.

This is an acute hospital with 500 beds and I carry out all aspects of the service autonomously, at an ATO grade. I feel this is well below what it should be for this post. mad

I notice that there are several vacancies for these posts all graded at MTO4 or 'G' grade. Is this typical? confused
