Indemnification is an agreement to protect another party from injury or loss. In practical terms, indemnification clauses in employment agreements usually state that the offending party must cover the injured party’s losses, which may include attorney fees.
Ideally, you should avoid indemnifying others, but the employer is unlikely to remove the clause entirely. In such a case the best you can hope for is that the clause will be reciprocal. That is, you indemnify the employer and the employer indemnifies you.
