• "at work" - use this when you're talking about something that's happening while someone is working:

• "in my job" - use this to talk about things that you have to do for work on a daily basis:

• "at my company" - use this to talk about large-scale things that are happening to the organization of the company you work for.

Things that don't have a clear purpose are unnecessary or unwanted:
