在我國抑或是世界其他的國家，肥胖的問題日趨嚴重，根據世界衛生組織（World Health Organization， WHO）的研究，2008年全球約有15億以上的超重成年人，其中有2億的男性和將近3億的女性體重已經達到所謂的「肥胖」，另外2010年全世界約有4300萬5歲以下的兒童超重 。綜上所述，肥胖的問題正影響著每一個社會。 肥胖者在日常生活中的食衣住行可能會受到一定的歧視與不便，由於可以討論的範圍過廣，本文僅聚焦在「就業上的肥胖歧視」。為了探討此問題，本文第二章說明何謂就業歧視，闡述肥胖者在就業上可能會面臨的歧視有哪些、主流群體對於肥胖的態度與刻板印象，最後論證國家就業上肥胖歧視的正當性與必要性。 第三章介紹美國法就業上肥胖歧視之解決途徑。在美國關於肥胖者於就業上受到的歧視，可能有三種法律救濟途徑。第一、可以尋找聯邦或是州法律有沒有在保護基於「身心障礙」之就業歧視；第二、他可以思考目前所面臨的「肥胖歧視」，得否繫於其他法律保護的歧視類型，例如：種族或是性別；第三、他可以尋找他所居住的州或是城市是否有針對肥胖歧視的直接立法？本文就美國聯邦與各州禁止身心障礙歧視的相關立法做初步的分析，並且帶出相關之判決；另本文亦分析某些州或城市直接禁止「肥胖歧視」之反歧視法與相關案例分析。 第四章則回到我國，分析我國目前法制關於就業上肥胖歧視之議題該如何處理，主要區分私人企業與國家兩種途徑，私人企業上，我們將著重在《就業服務法》第5條之規範，提出本文對於此條文用以解決肥胖歧視之利與弊；國家方面則從我國公務人員考試涉及BMI值判斷的合憲性。 最後第五章結論的部分，綜合分析美國法制與我國法制之間的異與同，最後提出個人對於此議題之建議，以期達到消弭就業上肥胖歧視之長遠目標。 / Obesity discrimination is a serious problem affecting millions of workers. Fat people, and fat women in particular, experience job-related discrimination in hiring, wages, and the terms and conditions of their employment. Hence, this research focus on the problem of obesity discrimination in employment. Part II defines "what is obesity?",and describes mainstream attitudes towards fatness, considers the empirical and anecdotal evidence demonstrating that fat people experience employment discrimination because of their obesity. Then discusses medical information about weight and health as well as weight loss in order to debunk the myth that being fat is always unhealthy and that weight loss is a viable or desirable outcome, this part concludes that being fat is immutable and deserve legal protection. Part III introduces American legal remedies. In America have three legal avenues to explore. First, someone could pursue an action under federal and state laws that protect people from employment discrimination based on disability or perceived disability. Second, someone could consider whether the weight discrimination he (or she) experienced was tied to him(or her) sex, race, or some other protected class. Finally, someone could determine whether any state or local law where he (or she) lived specifically prohibited weight discrimination in employment , since a few jurisdictions have included weight as protected category in their antidiscrimination laws. This part will discuss federal and state disability antidiscrimination laws and cases, and reviews antidiscrimination law passed by three earlier jurisdictions that specifically include weight as a protected category. Part IV discusses how to solve obesity discrimination in employment? This part separate privately owned businesses and national measure. In privately owned businesses, this part will focus on Employment Service Act Article 5 and analyze how to use Employment Service Act solve obesity discrimination in employment. On the side, this part will discuss on some national examinations have qualification restricted are constitutionally.
