Your use of the network, IM, and e-mail is a privilege, not a right. Violate this policy and, at a minimum, your access to the network, IM, and e-mail will be terminated, perhaps for the duration of your tenure with the Company.
Policy breaches include violating the above provisions, and failing to report violations by other users.
Permitting another person to use your account, password, or user ID to access the network, IM system, and e-mail system— including but not limited to someone whose access has been denied or terminated—is a violation of policy. Should another user violate this policy while using your account, you will be held responsible, and both of you will be subject to disciplinary action. Criminal violations may lead to criminal or civil prosecution.
