不一样,has been working强调继续进行的趋势,has already worked强调过去完成

都是我姐姐已经在这家公司工作，但是前者更强调一直，现在还在。后者现在是否还在不确定

第一句，我的姐妹一直在这家公司工作，现在完成进行时，表示从过去到现在一直是在这家公司工作，并且有以后会继续在这个公司工作下去的含义。
第二句，我的姐妹已经在这家公司工作了。这只是一个工作状态的描述（比如说，她毕业后想要来这家公司工作，但是可能工作经验不够，主管不招她，经过多方努力后，最后她如愿进入这家公司工作了。可能某一天有人问你：“你的姐妹进了那家公司了么？”你回答他说：“是的，她已经在那家公司工作了。”）当然这是一个情景设想，希望有助于你理解。
