I worked in the I.T. Division at a very high technical level for many years and can verify the offshore employees we had to train and support are a huge hinderance. They talk over you instead of listening and are extremely slow to learn. It is much easier to perform the work of two people than to be forced to drag an off shore employee through the process which they don't learn by anyway.
I agree with this 100%. Thanks for bringing this issue up on the board @Xvryggw-5uso
