If the 6% IAP Contribution is directed to the Pension plan, and if the collective bargaining language requires the employer to provide a 6% pay increase.  Making this change would actually cost more than the current plan.

For example, if an employee is currently paid $1,000 a month the employer send $76.50 (7.65%) to FICA, about $220 (22%) to PERs pension and $60 (6%) to the IAP, so the employee costs the employer $1,357 for the month.  If the IAP contribution is redirected and the employee has to provide a 6% pay increase, the employee's month pay becomes $1,060, $81 (7.65%) goes to FICA, $297 (28%) goes to PERS pension, $0 goes to the IAP and the employee now costs the employer $1,438 for the month, an increase of $81.

Unless the employer's resource have increased, this change results in less services being able to be provided by the employer.
