Bob Jeffrey, JWT's worldwide chief executive, and Michael Maedel, the worldwide president, are understood to have stepped in to ensure MacAuslan stays in an appropriate capacity.
The new conversations undermine the decision of JWT London's chief executive, Simon Bolton, to remove MacAuslan, who has been at the agency for 24 years, from his post. Bolton's move led Diageo, a client that works closely with MacAuslan, to voice concerns.
Bolton has fiercely denied numerous reports that there were any attempts to strip MacAuslan of his post.
MacAuslan, who will continue as the deputy chairman and managing partner until an agreement is reached, has yet to be formally offered a new position.
It is possible that JWT will offer him a global role working on the Diageo account.
It has yet to be determined whether he will retain the deputy chairmanship, which he has held since 1996 when he was promoted from head of account management.
