Businesses are legally required to have employers’ liability insurance in place when they have people working for them. This insurance is intended to cover situations where employees have been injured whilst at work.
As such, even if you are making a claim against your employer, it should be their insurers would will deal with the claim and pay out any compensation to you – rather than your employer themselves.
You will also have legal protection from negative consequences. If you were fired because of your claim, you would have a strong basis to claim for unfair dismissal, as dismissing someone for asserting their legal rights is not valid grounds to do so.
