Loyann,
  If the woman has her own office, why does she have to ask anyone's permission
to pump there?
  There are a few things to think about: What kind of relatinship does
she have with her supervisor, or whoever is next up in line? Can she
set up a meeting and try to talk with them about what the issues are?
Another thing to think about is the Human Resources or Employee Relations.
The job of HumanResources is to set and implement benefits policies.
Thejob of Employee Relations is to help workers and supervisors work
out disagreements and dificulties. People from either or both of these
"departments" should be able to help work out this issue.
  My experience is that *showing* companies the benefits of breastfeeding
and *showing* that it is not as difficult as one would think is the
best way to make these policies work. It may be some confort to this
new mother to know that she is probably blazing a trail for others and
the next mother who wants to nurse will have an easier time of it
in this workplace. That kind of encouragement can help women stick out
the fight too.
  Hope this helps. Keep us posted.
