The question Learning The Business was closed as Not Constructive.
I would like to know why because it is a good and constructive question to me. Moreover, one of the answerers voted to close. I am very confused. If you believe a question should be closed, of course you can vote to close if you have the voting right. But then, why do you bother to answer it?
Personally I think the question is constructive. Every new worker (not necessarily a new employee) could encounter this kind of situation at his workplace. You could be a senior employee but a new person to a new project. You're already familiar with the company procedures, rules, etc. However, you know nothing about the things you're working on. You'll need help. To acquaint yourself with the new project with all the help you can get is a key to your success at work.
How to get help is the answer OP is trying to figure out and that is my interpretation of this question. A typical answer may be that the manager is responsible. Also, the employee may have to request for it. We need everybody's experience and knowledge about this issue, such as from the manager's perspective, the senior tech lead's view, the employee's own experience, HR's opinion, etc. We can make it a community wiki if needed. But, why is it Not Constructive? To me, this question is much more constructive than "Is it rude to do X?".
