Any payment increase that is calculated as a multiplyer of RPI is in essence a cost-of-living related activity. Our pensionable pay increases are capped at a cost-of-living multiplyer limit. There is no mechanism to formally include any other factors, such as the level of profit the company made in the calculation... It becomes involved simply as a negotiation tool. Ts & Cs have also only become part of that negotiation due to the company not being willing to meet the cost-of-living rises without attaching strings.
