In 1971, 44 percent of workers who had been currently entitled to social security disability insurance (DI) benefits for 1 year or more also received benefits from at least one other source. Their average disability insurance benefit was higher than that of persons who received only DI benefits. On the average, total benefits to those receiving multiple benefits were double the amounts paid to those receiving only DI benefits. The combined benefits for the former produced median replacement rates about 50 percent larger than the median replacement rates for the latter. High replacement rates--defined here as more than 80 percent of predisability earnings replaced by benefit--predominate among those with multiple benefits. Considering replacement rates based solely on disability insurance benefits substantially understates the extent to which benefits from public and private programs actually replace predisability earnings. Replacement rates based solely on DI benefits are generally higher for those receiving DI benefits only than for persons receiving multiple benefits. Limiting DI benefits to the replacement rate from DI benefits alone is disadvantageous for persons who receive only DI benefits, compared with those who also receive other benefits.  相似文献

Employee attitude surveys are becoming an increasingly popular tool for employers. A host of legal implications, such as the circumstances under which they can be used, what they can ask, and whether or not they are a subject of mandatory bargaining, arise when surveys are conducted by companies that have an incumbent union or by companies that are involved in union-organizing campaigns. The following article describes the survey process, outlines some of the inherent advantages and pitfalls, and examines the legal questions raised when surveys are used by nonunion employers, by employers with incumbent unions, and by employers who are involved in union-organizing-campaigns. It concludes with recommendations for employers that undertake attitude surveys.  相似文献
