It appears that the lady is at first line sales manager {DM/SM/ASM/DO etc } and the sales team being referred to are agents/advisors or whatever these may be called. It is felt that except in case of Bharti Axa which pays some salary/fixed remuneration all other companies pay commission and some sales/performance linked incentives.
The insurance company sponsors the candidate and only sponsored candidates are allowed to undergo training and appear for exam conducted by III. Agent/Advisor declared having passed the exam signs an agreement with insurance company. IRDA grants license to sell insurance products.
These agents can terminate the contract, obtain NOC and be another company. IRDA has fixed some annual targets e.g. 12 policies, annual premium etc to be achieved. Usually if an agent does not log in business for some months company resorts to termination of contract. However due to poor returns from ULIP, mis selling, pressure selling by companies, banks, frauds; the business has taken a hit for all companies.
All companies are into poaching of agents.
The lady is otherwise in a position she can use to her advantage.
As far as leave etc are concerned insurance companies are following norms. Almost all companies keep leave rules, HR policy on employee portal/HR page, leave record of the employee on password protected employee page. Lady may join for a few days and avail annual leave. If the agents/advisors have been productive and are known to have good social circle company would like to retain them. BM/HO can transfer agents from one DM/SM/ASM/DO to another. If company is about to transfer agents it implies company has taken a decision to separate from DM/SM/ASM/DO. If the DM/SM/ASM/DO has a good social circle and is known to recruit from HNI clients and fetch policies from such clients company can decide to retain her. Lady may join for some time and apply to avail annul leave, LWP. While on leave she may firm up some recruitment /business and may log in while she joins. She should remain amiable with her BM, CM and her line management can help her. Let her negotiate in the business language.
