If your dream takes place at work it is most likely commenting on an issue at your workplace that you are trying to sort out.
Look at what is going on in your dream: are you falling behind? Are you getting in a fight? The action that happens in your dream is a direct reflection of something that is going on in your workplace.
If something won’t work in your dream, then it means something in your waking life isn’t working well. Ask yourself what situation in real life doesn’t seem to be working out or what part of your own personality isn’t working to your benefit.
