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' says the answer is hidden in the clue.
'OWE' is hidden within 'now employees'.
'to' acts as a 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" .)
