Worker with time to burn limited by great work schedule (5,5)
I believe the answer is:
gantt chart
'work schedule' is the definition.
(a Gantt chart is a type of schedule for a project)
'worker with time to burn limited by great' is the wordplay.
'worker with' becomes 'ant' (I can't justify this - if you can you should believe this answer much more).
'time' becomes 't'.
'to burn' becomes 'char' (charring is a kind of burning).
'limited by' indicates putting letters inside (limit can mean to contain or border off).
'great' becomes 'gt' (abbreviation used in place names).
'ant'+'t'+'char'='anttchar'
'anttchar' inserted within 'gt' is 'GANTT CHART'.
(Another definition for gantt chart that I've seen is " Diagram for production system".)
