Now employees have to be obliged (3)
I believe the answer is:
owe
'be obliged' is the definition.
(I've seen this in another clue)
'now employees have' is the wordplay.
'have' indicates a hidden word.
'OWE' can be found hidden inside 'now employees'.
'to' is the link.
(Other definitions for owe that I've seen before include "Are debtors" , "Have a debt to (someone)" , "Have obligation to pay" , "Be in debt - woe is me" , "Have to thank" .)
