Does an employee have to put any money in a police pension plan to receive his pension after he is 100 percent vested?

Yes, typically an employee must contribute to a police pension plan to qualify for benefits, even after becoming 100 percent vested. Vesting means the employee has earned the right to their benefits based on their years of service, but ongoing contributions are often required to maintain eligibility for pension payments. Specific rules can vary by jurisdiction and the terms of the pension plan, so it's important to consult the plan documents or a plan administrator for precise details.
