問 勞動者在(zai)剛入職(zhi)的時候，一般用人單位都會(hui)與之約定一個(ge)試用期，那么在(zai)這(zhe)種情(qing)況下(xia)只簽訂(ding)試用期合同是否有效(xiao)呢？

答 《勞動(dong)(dong)合同法》第十九(jiu)條：試(shi)用(yong)期(qi)(qi)(qi)包(bao)含在勞動(dong)(dong)合同期(qi)(qi)(qi)限(xian)內。勞動(dong)(dong)合同僅約(yue)定試(shi)用(yong)期(qi)(qi)(qi)的，試(shi)用(yong)期(qi)(qi)(qi)不(bu)成立，該(gai)期(qi)(qi)(qi)限(xian)為勞動(dong)(dong)合同期(qi)(qi)(qi)限(xian)。所以(yi)根據以(yi)上規定，單位(wei)如果只單獨約(yue)定試(shi)用(yong)期(qi)(qi)(qi)合同，該(gai)試(shi)用(yong)期(qi)(qi)(qi)合同不(bu)成立。
