I would advise you to take a thorough look at your employer's
acceptable usage policy or electronic usage policy or whatever you had
to agree to in order to work there.

What you are doing may be implicitly forbidden and you may be risking
termination by doing it.

Be very careful trying to circumvent the various protections put in
place, regardless of how easily they are bypassed.
