《工友》编辑部:我一年前退休,一家公司返聘我过去担任技术顾问。但是,从我到这家公司工作开始,公司和我从没有签订过劳动合同,也没有给我缴纳社会保险。每次我找公司的领导,领导就说我属于“发挥余热”的退休人员,不用签任何合同,公司也不用为我缴社保。请问,公司的说法符合法律规定吗?柯建国 “Coworker” Editorial Department: I retired a year ago and a company returned to employ me as technical advisor. However, from the very beginning of my work to this company, the company and I have never signed a labor contract, nor have I paid social insurance. Every time I look for a company's leadership, the leader says I belong to a retiree who “plays off the heat” and does not have to sign any contract. The company also does not have to pay for social security for me. Excuse me, the company's statement in line with the law? Ke Jianguo
