"The Level System is used as a threat"

The food here is better than the food at the last hospital I was at. It is cooked from scratch and prepared here, but in the NHS it is pre-cooked chilled. At my previous hospital there were more staff, however there are not enough staff here so some people don't get to go out. The level system is used as a threat. The staff will say to us If you don't do this thing then you will lose your leave. At the other hospital there was no level system and we got leave much; much quicker.
