我(wo)應聘的(de)是文員,現在公(gong)司讓我(wo)去銷售,實際(ji)崗(gang)位(wei)月合同(tong)中說的(de)崗(gang)位(wei)不符(fu)合同(tong)有效么?

勞(lao)動(dong)合同(tong)法(fa)規定(ding),用(yong)工第(di)一(yi)天,用(yong)人單(dan)位應當(dang)和勞(lao)動(dong)者簽訂(ding)書面勞(lao)動(dong)合同(tong),勞(lao)動(dong)合同(tong)中,崗位必須(xu)進行(xing)明確,除非雙方協(xie)商同(tong)意(yi),否則(ze)單(dan)方無(wu)權更改。
