Dismay of company people having to accept authoritarian (13)
I believe the answer is:
consternation
'dismay' is the definition.
(thesaurus)
'company people having to accept authoritarian' is the wordplay.
'company' becomes 'co' (abbreviation).
'people' becomes 'nation'.
'having to accept' indicates putting letters inside.
'authoritarian' becomes 'stern' (I've seen this before).
'nation' placed around 'stern' is 'nsternation'.
'co'+'nsternation'='CONSTERNATION'
'of' is the link.
(Other definitions for consternation that I've seen before include "Dismay - cast-iron tenon (anag)" , "Alarm" , "Feelings of dismay" , "Worry" , "Anxiety, dismay" .)
