The point is...they should not be carrying their TLD with them from job to
job except in cases like Doug Atkins

Therefore, an employer that requires an employee
to travel, say by jet aircraft at high altitudes, is supposed to account for
the high altitude exposure (not natural background, per se, but maybe enhanced
by the high altitude of the flight) and the additional exposure from
penetrating x-rays at the airport....really?

A dosimeter is
issued to an individual to monitor occupational dose received at a
specific facility. Taking it to a different facility can lead to
attributing dose to the wrong facility. For NRC-regulated
operations, this would probably be regarded as a CFR
violation.
Actually, what the regs say is: "Occupational dose
means the dose received by an individual in the course of employment in
which the individual's assigned duties involve
exposure to radiation or
to radioactive material from licensed and unlicensed sources of radiation,
whether in the possession of the licensee or other person. Occupational dose
does not include dose received from background radiation, from any medical
administration the individual has received, from exposure to individuals
administered
radioactive materials and released in accordance with Sec.
35.75, from
voluntary participation in medical research programs, or as
a member of
the public."
Again: "exposure...from licensed
and unlicensed sources of radiation, whether in the possession of the
licensee or other person."
That is, ALL licensees, must account for
ALL dose, with exceptions noted in the definitions (i.e., background,
medical exposures, etc.). If YOU are the licensee that knocks a person
over the limit, even if they're getting dose from five other licensees, YOU
are the responsible party.
