It was difficult to let my voice be heard to upper management. Communication. For example, I have told my team leader about a problem and he was unsure of how to fix it. So he tells me he will talk to management and get back with me. A week later, I never hear anything. In addition, I go directly to management to ask about it and they tell me its the first they heard of the problem. This has happened with more than one manager, team leader or co-worker. As a part timer, it can be hard to make a living and get more than 30 hours. There were times in January, I got 15 hours a week several years in a row.
