回复：It is not right time to 获得其它部门的工作经验 right now.

In this current bad economy situation, you should focu on yon own job. You may ask to do so when economy situation returns to normal.

Two reasons:

1. You show your boss you don't like your current job.

2. People does not like to share their skills/secret with others especially right now because
they worry about losing their jobs once someone can do their jobs.
