Nah.. if you have a "lets get things done" team then that co-worker might love you. If you've saved them time, then word might get out that you've helped them.

Nah.. if you have a "lets get things done" team then that co-worker might love you. If you've saved them time, then word might get out that you've helped them. If the other person tells your manager it will be "X helped me so much." They might start asking you to help with other things. Others will hear about it, not as you're trying to step on them, but that you're making their life easier. You could become the "go to person". Then you might get some time to study on the company dime.
