Here are a couple other phrases that could be re-worded on a more work-friendly manner:
- Instead of saying, "Get me off this email chain", you can say, "Kindly exclude me from future communications, and don't hesitate to include me again if my participation becomes necessary."
- Instead of saying, "That sounds like a horrible idea", you can say, "Are we confident that this is the most optimal solution or are we still considering other alternatives."
- Instead of saying, "I don't get paid enough to deal with that", you can say, "That goes beyond what can reasonably be expected within the responsibilities of my position."
- Instead of saying, "What do you want?", you can say, "Is there something specific that you need from me?".
