1. unskilled labour
2. unqualified
I am quite unqualified to teach them.
Tom is unqualified for that job.
Beth is unqualified for such a responsible post.
My first task was to screen out unqualified applicants.
3. menial
Tourism provides people with jobs but often rather menial ones.
a menial job in the restaurant's kitchen
menial work
My parents work at menial jobs and are given no respect.
menial jobs or tasks are not very difficult, do not require any skill, and the people who do them have very low status
menial work is boring, and not well paid or respected
Immigrants often take menial jobs that no-one else wants.
