I can remember back to when secretaries were effectively the typing pool.
I don't agree that secretaries will disappear to be outsourced to India - there will always be a role for a PA who provides a combination of secretarial, small project management for the boss, managing the diary and access to the boss. I don't see how that can be outsourced.
If you are in the same law firm where it didn't work out before, I agree you are perhaps unlikely to get a second bite at the legal aspects.
