Make sure you completely understand what your boss is asking before saying 'no.' Example: “I have several urgent projects right now, and I’m worried I can’t give this new task the attention it needs.”
Politely explain why you can’t do it, making sure your reasons are clear and truthful. Example: “I have several urgent projects right now, and I’m worried I can’t give this new task the attention it needs.”
Offer other ways to get the job done. Example: “Maybe (colleague’s name) can help with this? Or we could adjust my current tasks.”
Let your boss know your workload limits ahead of time. Example: “I’m at full capacity with my projects. Can we discuss this later?”
Request help in deciding which tasks are most important. Example: “I’m happy to help, but I need to know which projects should come first.”
Explain how taking on too much could lower the quality of your work. Example: “I want to do my best work, but taking on more might reduce quality.”
Show you’re willing to help within your limits. Example: “I can’t take on this project right now, but I can assist in a smaller way.”
