Working from home can be a good idea, especially if you find travelling difficult or you have good days and bad days with your health. Before you work from home, think about the issues you could face and how you could manage them.
Talk to your employer about what you might need to work from home, such as:
a space to work undisturbed
a reliable internet connection (your employer might pay part of your broadband bill)
You should ask your employer about the tools you might need to work from home. If your condition means that you need to work from home, this could be a reasonable adjustment. Your employer should check the place where you work to make sure that it's a safe working environment.
