Microwaving salmon at work can be considered rude or inconsiderate to your colleagues due to the strong smell it can produce. Salmon has a distinctive odor that can linger in shared spaces, such as break rooms or office kitchens, and may be unpleasant for others who are sensitive to smells or have dietary restrictions. It's generally a good idea to be mindful of the communal environment and respect the preferences and sensitivities of your coworkers when it comes to food choices. If you still wish to enjoy salmon for lunch, you might consider consuming it in a different location or finding alternative cooking methods that minimize the smell, such as baking or grilling it at home before bringing it to work.
