Answer:
No, it's not retiliation, it's part of the employers responsability.
Step-by-step explanation:
The incentive program was informed before the accident even took place. The employer is required to pay close attention and make sure all safety rules are being followed and assure the employee's health is under no risks. The incentive in the example promotes following safety rules, however, if the employee doesn't follow them, is under his/her own responsibility, but the employer has to find a legal way to enforce them, like removing the incentive in this case.
