Handling Resignation Emails from Client-Provided Addresses
If a resource has been working with your organization and, for whatever reason, is unable to use your company email ID, they should use a public email ID at most, but not the client email ID. Using a client email ID indicates ignorance or carelessness towards your organization, especially if the employee is joining the client organization from where they sent the mail.
Now, it is up to you whether you excuse the employee for the mistake or reject their email, stating that they must comply with the organization's policies.
If your employee is deputed at the client site, generally the client provides an email ID for confidentiality and security of information. It is possible that your employee has joined the client organization without intimation. If this situation is true, there are a few concerns:
1. Your employee might have joined the client organization without resigning from your organization. This is illegal. Do you have procedures in place to address this?
2. You have little binding on your employees, which makes your organization more vulnerable to an increased rate of attrition. You need to have strong policies and controls to ensure that your employees who work for clients do not leave your organization halfway when the client offers better opportunities.
3. The client is indulging in poaching your resources. You need to discuss with the client and get such practices restricted or compensated. Either the client should stop recruiting your resources or agree to pay an amount to compensate for the training, maintenance, and salary of the resource poached from you. You need to have an agreement with them.
It is not mandatory to get hard copy resignations. Today, electronic evidence is enough for policy compliance. One has to accept responsibility and accountability for their email.
