Making pension debt super-priority in bankruptcy and restructuring would go a long way to solve this problem and provide pension security. Under the Wage Earner Protection Program introduced by the Conservative government in 2008/9 normal pension contributions for the year of bankruptcy were granted super-priority status. A good start, but not far enough. Super-priority status should be extended to the entire pension so the pension gets addressed as a high priority whether the company declares bankruptcy under the Bankruptcy and Insolvency Act or restructures under the Companies' Creditors Arrangement Act. 
Super-priority is one of the few financial terms common in both. Not even secured and unsecured creditors are common.
