Employers usually aren’t concerned whether you were at fault or the victim of an accident. Instead, what matters more is their ability to fulfill the obligations you left behind and ensure the work gets done.
If you are unable to work and you lose your job as a result of your car accident, you may recover lost income while you recover and look for another job. One thing to keep in mind is that you may need to provide evidence that you were or are looking for a job. In most cases, you are not entitled to sit by and not look for a job and still recover lost pay. This is known as mitigating your damages. You will want to be able to prove your effort to find a new job.
