The tortfeasor shall receive a credit against his or her liability to the plaintiff in an amount equal to the amount of contribution, if any, for which the employer is found to be liable to that tortfeasor, even if the amount exceeds the employer's liability under the Workers' Compensation Act or the Workers' Occupational Diseases Act.

(b) This Section does not apply in any action in which the plaintiff's employer has no right of reimbursement from the plaintiff under subsection (b) of Section 5 of the Workers' Compensation Act  3 or subsection (b) of Section 5 of the Workers' Occupational Diseases Act.  4

(c) This amendatory Act of 1995 applies only to causes of action accruing on or after its effective date.
