Directors of Norwich Union (NU) and RAC this week escaped a cull which will see 1,700 jobs go across the two companies.
But the process of determining which lower-level employees at NU and RAC will lose their jobs will now begin in earnest, after Aviva announced the new director structure of the two companies.
An NU spokesman said: "The directors of the individual areas of the business will now look at what structural changes they wish to see implemented and inevitably some job losses will follow. We expect to know more over the next few weeks."
NU has named George Berrie as intermediary director, following the retirement of Ken Wallace.
John Seaton has retained his position as underwriting director, but will now also have jurisdiction for RAC.
Teresa Copping will keep her position as claims and operational service director and John Kitson will remain as consumer director.
RAC has seen its executive structure left largely unchanged. The RAC board will report to Simon Machell, who replaced Andy Harrison as managing director of the motor services provider following Aviva's £1.1bn buy-out.
