试用期该多长问:辽阳郑欣——我2008年大学毕业以后,就进了一个企业。起初单位和我约定试用期为三个月,可三个月后领导换届,新领导不但不和我签劳动合同,还要求我再试用一段时间。我觉得他们这样做不合理,所以想跟您咨询一下,《劳动法》里有没有对我这种情况的规定? Long probation period Q: Liaoyang Zheng Xin - I graduated from college in 2008 after entering a business. Initially, the unit agreed with me for a probationary period of three months. After three months, the leadership reelected. The new leader not only signed a labor contract with me, but also asked me to try for some time. I think they have done so unreasonably, so I would like to consult with you on whether there is any provision in the Labor Law about my situation.
