This question already has an answer here:
About 3 months ago, I left a secure work-from-home job for one with a greater challenge, more money, and a significant commute.
Although I don't yet have access to the application I'm supporting, I've read all available documentation, and used every self-help method I could find, in order to get up to speed.
I've helped with one small project, and was able to learn a lot about the system and the business. It went well, but I learned that the business controls projects and their deadlines. Since that project went live over a month ago, I have had not a single piece of new work.
I've delicately broached the subject with my boss, who is complaining of the same thing. She says we'll have work soon, but I don't know how to fill my 8-hour days until then.
I have to account for my time, and allocate it to line items for projects. I'm full-fledged lying, because I have nothing to work on.
I'm frustrated, but I'm trying to be patient. I have thought about asking other areas if I can help with anything, but a) I'm afraid of making too much "noise" about my lack of work, b) I don't want to go over my manager's head, and c) I don't know what benefit I would provide, since I'm new to the company.
