Workplaces should be safe. You have a right to expect your coworkers to adhere to safe workplace guidelines. Your employer is required to provide all the training and equipment necessary to prevent injuries.
Workplace injuries can and will happen, even when you, your employer and your coworkers are adhering to safety guidelines. If your employer isn’t treating your injury fairly, is trying to punish you for filing a claim or is trying to change the narrative to protect themselves at your expense, you should seriously consider speaking with a workers’ compensation attorney.
