When an injury occurs at work, you are entitled to a worker's compensation claim. It's not wrong to file this claim, in fact, it is improper not to. The reason is because all employers are required to purchase insurance to cover injuries to employees and if the claims are not filed, then the employer should not be required to have insurance for this.
It is illegal for an employer to fire or take any adverse action against an employee for filing a work injury claim or even to make the employee feel uncomfortable in doing so. Employees are entitled to receive wages while they are out of work as well as a potential "lump sum" settlement for any wages not recovered and the pain and suffering endured. The law does not permit you to sue your employer for a work injury and you don't have to- If you sustain and injury at work for almost any reason, you are entitled to recover benefits. If the injury is the fault of some other party, you are also likely entitled to an additional claim, known as a "3rd Party" Claim. It is important to contact an Injury Firm that handles all aspects of work injuries so you know all of your rights and options.
