    • To commit the organization to a third party for example through purchase or sales contracts, job offers, or price quotations, unless you are explicitly authorized by management to do so (principally staff within Procurement and HR). Do not interfere with or remove the standard corporate email disclaimer automatically appended to outbound emails;
    • For private or charity work unconnected with the organization’s legitimate business;
    • In ways that could be interpreted as representing or being official public statements on behalf of the organization, unless you are a spokesperson explicitly authorized by management to make such statements;
