If you can’t get to work because of the floods or damage to the roads, you should tell your employer as soon as possible. What is reasonable here will depend on the circumstances – in the case of natural disaster, what is reasonable might be less notice than you’d normally be expected to give.
You have the right to ask your employer for changes to your working arrangements. This can be about when you do your work (which days or hours) or where you do your work (for example, working from home), or both.You and your employer should discuss in good faith what other options are available, like working from home temporarily.
The law says your employer can refuse your request only if they can’t make the changes fit with the business’s operations. However, this is a subjective test. If your boss says it’s not going to work due to their business operations, you can’t challenge or review this decision.
You can also talk with your employer about taking leave until you are able to return to work if flexible working arrangements aren’t an option
