The worst job I ever had was working in the social security office, before computerisation, matching post to case files. Every morning I was given a long list of names to locate their files. The problem was that the filing cabinets were bursting so files were piled on top of cabinets in wobbly towers. Files could also be “ out” meaning on someone’s desk . There was no guarantee the individual even had an existing file! However hard I worked I could never get to the end of the list before a new set of names were added.
