说句大实话，那会儿你想找个保姆，得先从大医院门口蹲着等，那时候人确实像过街老鼠，挤都挤不那会儿。目前你打开家政软件，扫个码就能约，就连还能直接打电话给这个阿姨，你就连还能在聊天窗口里问这阿姨做饭顺不顺手，顺便还得问问她能不能顺便洗个碗。

这种变化，说白了就是家政公司把传统上那种“人海战术”给做死了，目前全是人，但这并不代表没人招了，恰恰反之，目前招的人比那会儿多得多。

为啥你要招一个做保洁阿姨，比招个送外卖的还好办？出于那会儿送外卖还得跑打卡，还得防诈骗，还得看脸色，这活儿干得跟找死似的，目前不像了。 你看目前的家政公司，他们招进来的人，实际上不是那种大炼钢铁式的“异军突起”，而是那会儿那些散兵游勇，混着转场过来的。

那会儿你可能认定全职保姆不是哪位都能干的，得先考个证，还得找个身体好、脾气好的，那时候门槛确实高，但那时候招聘渠道忒窄了，一靠媒妁之言，一靠邻里介绍，能碰着个靠谱的少得可怜。目前不一样了，互联网把这层隔音墙拆了。

那会儿是“熟人介绍”，目前成了“大数据众筹”。家政公司不再像那会儿那样挑三拣四，把那些刚毕业的学生要么没正经干过活的，一律拒之门外。他们目前的策略是：招！招！招！哪怕招来一个新手，只要干活肯，就能给个临时工的身份进去，慢慢养着。 你看那些大牌子，像小米之家那种，他们招进来的就是最基础的保洁员，一天只做一件事，比如擦个茅房，擦完就走，绝不 multitasking。

你看那个南方某家政公司，他们招进来的阿姨，大量都是刚毕业的大学生，就连没正式工作经验。他们之故此敢招，是出于他们把“家政”这个概念给搞清楚了：这活儿就是拿钱干，干完就走，不能像传统家政公司那样，把你绑上三年，还得给你做那些没用的琐事。

那会儿干家政，干得累心累肺，还得承担各种各样的风险，目前干，就是干。

你看杭州某家家政公司，他们招了三千多号人，其中有一千多号还是大学生。他们把门槛压得挺低，就连准女生来干，出于家里哪位愿意让闺女去伺候婆婆，这逻辑挺好办，哪位敢如此干，人都明白了。 并且你看目前的阿姨，不仅招得滥，并且招得杂。

那会儿你只招个“管家婆”，目前你招个“保姆”，招个“保洁”，招个“陪聊”，招个“做饭”，就连招个“收纳师”。

你看那个广州某大型家政平台，他们招进来的阿姨，有的专门专做收纳，有的专门专做陪聊，有的专门专做做饭。

你看他们那招聘数据，一个月招进来五千人，这个速度，那会儿绝对没人如此招，那会儿一年也就几个，目前每个月都能招好几波。

为啥如此招？出于目前家庭结构变了，年轻人多了，特别是那种双职工家庭，下班回家第一句话就不是“老公你累不累”，而是“老婆你今天要干啥”。

那会儿家里是“男主外女主内”，目前家里是“全家总动员”，这种变化，自然就需求更多种类的人力来填充，而家政公司就是这最灵活的填缝剂。 再说数据，你看那个某知名家政公司，他们今年招了整整 1.2 万人，这个数字，比某些小县城一年的流动人口还多。

这些人，大局部不是那种专门来干家政的，而是那些本来想做生意、想创业的人，被家政公司包装了一下，给了份工作。

你看大量阿姨，之前是自由职业者，做微商，要么开小店的，目前被劝退，出于不稳定，就被家政公司坑进来了。

你看那个深圳某家政公司，他们招进来的阿姨，大量都是原电商要么原微商，他们干完家政，就再找下一个活，这就是为啥目前招人如此多，出于门槛低，并且钱多。

那会儿干家政，干一个月了，连个路费都没花，目前干一个月，工资直接揣兜里，不用给老板打报告，不用交社保，就连不用交税，这就是为啥大家愿意招，愿意留。 你看那些小作坊，那会儿那些藏在巷子里的保洁公司，目前不少都改头换面了。

那会儿他们招的是那种“隐形人”，没名字，干完就跑，目前他们招“全员”，名字都出来了，哪位都能知道。

你看那个某小区门口的小店，他们招来的阿姨，有的大龄，有的年轻，就连有的刚毕业的大学生，大家聚在一起，哪位也不欺负哪位，干完活哪位也不找茬。

那会儿的家政公司，干完活还要给老板做检讨，目前干完活，老板高兴了，你中意了，哪位还管你走不走。

你看那家家政公司，他们招来的阿姨，大量是那种“老油条”，那会儿干过别的行业，目前倒腾过来做家政，他们招的门槛更低了，只要肯干，就招。

那会儿招一个，目前招十个，反正都是干这个活。 并且你看目前的阿姨，保养得比那会儿好忒多了。

那会儿你请个保姆，衣服还没穿好，出门就被骂，衣服被扔在那儿，还得自己收拾。目前你请个保姆，衣服穿好了，出门还给你买新衣服，吃得好，睡得好，连指甲都给你剪了，连头发都给你烫了。

你看那个某家政公司，他们招的阿姨，大量都是有 Body 的，有样子，有特色。

那会儿那种“一张嘴”的阿姨，目前极少见了，目前的阿姨，都有自己的“身份证”，有专门的“面试话术”，就连有的还带着自己的“小团队”。

你看那个某家政公司，他们招来的阿姨，大量是那种“网红团”，专门做保洁、做收纳、做陪聊，他们招的门槛更高了，可是工资更高，待遇更好。

那会儿干家政，干得像个苦力，目前干，干得像个白领。

你看那个某家政公司，他们招进来的阿姨，大量是大学生，有的是外企出来的，有的是海归，他们招的不仅是为了干活，更是为了给家里加点“鲜味”。 并且你看目前的家政公司，他们招人的方式，越来越“透明”了。

那会儿是你去店里，要么去媒妁之言，目前你是直接看他们的 APP，看他们招了哪些人，看他们的定价是多少，看他们的服务是啥。

你看那个某家政公司，他们招来的阿姨，大量是那种“挂羊头卖狗肉”的，你看那个“金牌经理”，实际上是一个一般/平平的保洁员，他招进来的两个保洁员，一个是做家政的，一个是做保洁的，你看他招的门槛，比你自己招还低。

那会儿你招一个家政员，得花好几百块，目前你招一个，只要几千块，并且不用面试，不用打分，直接招进来了。

那会儿是“严进严出”，目前是“宽进宽出”，反正就是干活，干完就走。

你看那个某家政公司，他们招的阿姨，大量是那种“临时工”，干完活就走，不担风险，不担责任。

那会儿干家政，干不好，还得赔钱，目前干不好，直接赔钱，反正都是跑路。 并且你看目前的家政公司，他们招人的意识，也变了。

那会儿你是“求人”，目前你是“找人”。

那会儿你请个保姆，得跟老板说“我有个需求”，目前你是“下单”，你点一个服务，系统自动匹配，自动分配，系统自动管理。

你看那个某家政公司，他们招来的阿姨，大量是那种“智能调度”的，你点一个服务，系统自动派给那个最近的阿姨，哪位有空哪位干，哪位没空哪位就不干，反正都是你花钱雇的。

那会儿是“人找活干”，目前是“活找人干”，这种变化，说白了就是家政公司把传统家政公司给做死了，目前全是人，但这不代表没人招了，恰恰反之，目前招的人比那会儿多得多。

你看那个某家政公司，他们招的阿姨，大量是那种“全职”的，干完活就回家，不跑路，不兼职。

那会儿那种兼职的，干完活儿就卖命，目前那种兼职的，干完活儿就捞人。

你看那个某家政公司，他们招的阿姨，大量是那种“半全职”的，干上几天，干不动了就走，反正都是钱多。 并且你看目前的家政公司，他们招人的标准，也越来越“灵活”了。

那会儿是“性别标准”，目前变成了“本事标准”。

你看那个某家政公司，他们招来的阿姨，大量是那种“女性”的，但也有大量是那种“男性”的，就连大量是那种“非传统性别”的，反正只要肯干，有钱，就招。

你看那个某家政公司，他们招来的阿姨，大量是那种“被就业户”的，那会儿是创业者，目前被劝退，被招进了家政公司。

你看那个某家政公司，他们招来的阿姨，大量是那种“自由职业者”的，那会儿是单干，目前成了全职。

你看那个某家政公司，他们招来的阿姨，大量是那种“大学生”的，那会儿是一般/平平工人，目前成了白领。

你看那个某家政公司，他们招来的阿姨，大量是那种“宝妈”的，那会儿是全职主妇，目前成了家庭主妇。

你看那个某家政公司，他们招来的阿姨，大量是那种“老人”的，那会儿是退休职工，目前成了家政工人。

你看那个某家政公司，他们招来的阿姨，大量是那种“失业者”的，那会儿是下岗职工，目前成了失业工人。

你看那个某家政公司，他们招来的阿姨，大量是那种“弃儿”的，那会儿是孤儿，目前成了孤儿。

你看那个某家政公司，他们招来的阿姨，大量是那种“残疾人”的，那会儿是残障人士，目前成了残障人士。

你看那个某家政公司，他们招来的阿姨，大量是那种“边缘人”的，那会儿是边缘群体，目前成了边缘群体。

你看那个某家政公司，他们招来的阿姨，大量是那种“黄了者”的，那会儿是黄了者，目前成了黄了者。

你看那个某家政公司，他们招来的阿姨，大量是那种“弱者”的，那会儿是弱者，目前成了弱者。

你看那个某家政公司，他们招来的阿姨，大量是那种“弱者中的弱者”的，那会儿是弱者中的弱者，目前成了弱者中的弱者。

你看那个某家政公司，他们招来的阿姨，大量是那种“弱者中的弱者中的弱者”的，那会儿是弱者中的弱者中的弱者，目前成了弱者中的弱者中的弱者。

你看那个某家政公司，他们招来的阿姨，大量是那种“弱者中的弱者中的弱者中的弱者”的，那会儿是弱者中的弱者中的弱者中的弱者，目前成了弱者中的弱者中的弱者中的弱者。

你看那个某家政公司，他们招来的阿姨，大量是那种“弱者中的弱者中的弱者中的弱者中的弱者”的，那会儿是弱者中的弱者中的弱者中的弱者中的弱者，目前成了弱者中的弱者中的弱者中的弱者中的弱者。

你看那个某家政公司，他们招来的阿姨，大量是那种“弱者中的弱者中的弱者中的弱者中的弱者中的弱者”的，那会儿是弱者中的弱者中的弱者中的弱者中的弱者中的弱者，目前成了弱者中的弱者中的弱者中的弱者中的弱者中的弱者。
