Cooks accommodating current bosses (6)
I believe the answer is:
chiefs
'bosses' is the definition.
('chief' can be a synonym of 'boss')
'cooks accommodating current' is the wordplay.
'cooks' becomes 'chefs' (chef is a kind of cook).
'accommodating' means one lot of letters goes inside another.
'current' becomes 'I' (physics symbol).
'chefs' going around 'i' is 'CHIEFS'.
(Other definitions for chiefs that I've seen before include "Leaders, heads" , "Bosses, gaffers" , "Leaders, bosses" , "Heads top dogs" , "Leaders, bigwigs" .)
