Nervous about my boss, for example, getting upset (2,4)
I believe the answer is:
on edge
'nervous' is the definition.
(on edge can mean nervous or tense)
'about my boss for example getting upset' is the wordplay.
'about' becomes 'on' (as in a book 'on' a certain topic).
'my boss' becomes 'ed' (abbreviation for editor, the setter's boss).
'for example' becomes 'eg' (short for 'exempli gratia', 'for example' in Latin).
'getting upset' is a reversal indicator.
'eg' back-to-front is 'ge'.
'on'+'ed'+'ge'='ON EDGE'
(Other definitions for on edge that I've seen before include "Under stress" , "Highly strung" , "Nervous and tense - close to cliff?" , "Cliff-top walker may be" , "Anxious, nervy" .)
