Tables to work at (5)
I believe the answer is:
desks
'tables' is the definition.
(desk is a kind of table)
I don't understand the remainder of the clue.
Can you help me to learn more?
(Other definitions for desks that I've seen before include "Office tables" , "Office equipment" , "Work tables" , "Furniture at which to read, write etc." , "Workstations" .)
