The decline in American manufacturing is a common refrain, particularly from Donald Trump. “We don’t make anything anymore,” he told Fox News, while defending his own made-in-Mexico clothing line.
Without question, manufacturing has taken a significant hit during recent decades, and further trade deals raise questions about whether new shocks could hit manufacturing.
But there is also a different way to look at the data.
Across the country, factory owners are now grappling with a new challenge: Instead of having too many workers, they may end up with too few. Despite trade competition and outsourcing, American manufacturing still needs to replace tens of thousands of retiring boomers every year. Millennials may not be that interested in taking their place. Other industries are recruiting them with similar or better pay.
For factory owners, it all adds up to stiff competition for workers – and upward pressure on wages. “They’re harder to find and they have job offers,” says Jay Dunwell, president of Wolverine Coil Spring, a family-owned firm. “They may be coming [into the workforce], but they’ve been plucked by other industries that are also doing as well as manufacturing,” Mr. Dunwell has begun bringing high school juniors to the factory so they can get exposed to its culture.
At RoMan Manufacturing, a maker of electrical transformers and welding equipment that his father cofounded in 1980, Robert Roth keeps a close eye on the age of his nearly 200 workers. Five are retiring this year. Mr. Roth has three community-college students enrolled in a work- placement program, with a starting wage of $13 an hour that rises to $17 after two years.
At a worktable inside the transformer plant, young Jason Stenquist looks flustered by the copper coils he’s trying to assemble and the arrival of two visitors. It’s his first week on the job. Asked about his choice of career, he says at high school he considered medical school before switching to electrical engineering. “I love working with tools. I love creating,” he says.
But to win over these young workers, manufacturers have to clear another major hurdle: parents, who lived through the worst US economic downturn since the Great Depression, telling them to avoid the factory. Millennials “remember their father and mother both were laid off. They blame it on the manufacturing recession,” says Birgit Klohs, chief executive of The Right Place, a business development agency for western Michigan.
These concerns aren’t misplaced: Employment in manufacturing has fallen from 17 million in 1970 to 12 million in 20When the recovery began, worker shortages first appeared in the high-skilled trades. Now shortages are appearing at the mid-skill levels.
“The gap is between the jobs that take no skills and those that require a lot of skill,” says Rob Spohr, a business professor at Montcalm Community College. “There’re enough people to fill the jobs at McDonalds and other places where you don’t need to have much skill. It’s that gap in between, and that’s where the problem is.”
Julie Parks of Grand Rapids Community College points to another key to luring Millennials into manufacturing: a work/life balance. While their parents were content to work long hours, young people value flexibility. “Overtime is not attractive to this generation. They really want to live their lives,” she says.

【背景资料】某高速公路第五施工合同段地处城郊,主要工程为路基填筑施工。其中K48+010~K48+328段原为路基土方填筑,因当地经济发展和交通规划需要,经各方协商,决定将该段路基填筑变更为(5×20+3×36+5×20m)预应力钢筋混凝土箱梁桥,箱梁混凝土标号为C40。变更批复后,承包人组织施工,上部结构采用满堂式钢管支架现浇施工,泵送混凝土。其施工工艺:地基处理→支架系统搭设→(A)→安装底模→(B)→调整标高、安装侧模→底板、腹板钢筋加工安装及预应力管道安装→内膜安装→顶板钢筋加工安装、端模及锚垫板安装→预应力筋制作安装→浇筑箱梁混凝土→养护→预应力张拉→孔道压浆、封锚→拆模及支架。
事件1:支架施工时,施工单位考虑了结构本身需要的预拱度和施工需要的预拱度两部分。其中对施工预拱度设置考虑了以下因素:①模板、支架承受施工荷载引起的弹性变形;②受载后由于杆件接头的挤压和卸落装置压缩而产生的非弹性形变;
事件2:在箱梁混凝土现浇施工时,梁体混凝土在顺桥向宜从高处向低处进行浇筑,在横桥向宜对称浇筑。混凝土浇筑完成后,洒水养护7d。
事件3:张拉预应力筋,:采用“双控法”控制,余露预应力筋采用电弧切割,并留30mm外漏长度,箱梁采用洒水覆盖养护;箱梁混凝土强度达到规定要求后,进行孔道清理、预应力张拉压浆,当灰浆从预应力孔道另一端流出后立即终止。
事件4:箱梁现浇施工正值夏季高温,为避免箱梁出现构造裂缝,保证箱梁质量,施工单位提出了以下三条措施:(1)选用优质的水泥和骨料;(2)合理设计混凝土配合比,改善骨料级配、降低水灰比、掺和粉煤灰等;(3)严格控制混凝土搅拌时间和振捣时间。
2018年11月1日,张某应聘到甲公司工作,并签订了书面劳动合同,合同主要内容包括:
合同期限2年;工资3500元;试用期6个月,试用期内工资为3000元。
合同签订后,甲公司又要求张某缴纳2500元抵押金,原因是防止公司职工在合同期内随意跳槽。张某因一时找不到合适的工作,即缴纳了抵押金。
2020年10月31日,张某的劳动合同到期,甲公司与张某续签了一份3年期的劳动合同,约定试用期为1个月,并退回了抵押金。由于公司效益比较好,2020年12月,张某提出要与公司签订无固定期限劳动合同,公司没有同意。张某随后提交了辞职报告,双方一致同意解除了劳动合同。张某要求甲公司支付劳动合同解除的经济补偿,被公司拒绝。
已知:甲公司所在地最低月工资标准为1800元。
要求:根据上述资料,不考虑其他因素,分析回答下列小题。
2. 甲公司与张某约定的下列试用期条款中,符合法律规定的是( )。
某股份有限公司 2020 年 1 月初股东权益总额为 18000 万元,其中:股本为 10000 万元(股数 10000万股,每股面值 1 元),资本公积(股本溢价)为 3000 万元,盈余公积为 4000 万元,未分配利润为 1000 万元。2020 年发生与股东权益有关的业务如下:
(1)2 月 20 日,股东大会批准了上年度利润分配方案,按每 10 股 2 元发放现金股利,共分派 2000 万元现金股利,其中动用未分配利润 1000 万元、盈余公积 1000 万元。
(2)3 月 4 日,委托证券公司公开发行普通股 3000 万股,每股面值 1 元,每股发行价格 4 元。合同约定,按股票发行收入的 3%向证券公司支付佣金并从股票发行收入中扣除。扣除佣金后的股票款已收到变存入银行。
(3)3 月 5 日,经股东大会批准,以资本公积 3000 万元转增股本。
(4)12 月 24 日,经股东大会批准,以银行存款回购本公司股票 2000 万股并注销,每股回购价为 5.5 元。
要求:根据上述资料,不考虑其他因素,分析下列问题。(答案中的金额单位用万元表示)
根据资料(2),下列各项中,该公司发行普通股的会计处理结果正确的是( )。
【背景资料】甲铁矿为地下矿山,共有员工780人,拟对该矿的尾矿库进行加高扩容工程四期建设,该尾矿库采用湿式放矿、上游式筑坝,初期坝高20m、坝底标高+400m,堆积坝最终标高+560m,每级子坝高5m、台阶宽5m,全库容1700×10⁴m³。2016年1月,委托某安全评价公司完成了《安全预评价报告》,2016年1月24日,该矿组织专家对《安全预评价报告》进行了评审并予以通过。2016年3月,该矿委托某设计院出具《变更安全设施设计》。2016年4月,有关安全生产监督管理机关组织通过了《变更安全设施设计》评审。2016年4月25日该矿以包工包料形式委托给乙公司组织施工。
2016年5月10日开始施工。2017年3月11日中班,乙方项目部安排朱某、成某等6名工人,在坝上进行膜袋灌沙、扎口及排水作业,18时30分,甲方夜班巡坝工严某、郭某按照班组管理制度要求到达现场进行了正常交接班,2人均按照巡检周期(2h)对坝体进行巡查一次,巡查过程中未见异常情况。12日凌晨2时10分正在进行膜袋施工的朱某和成某,发现其所处工作区域(北部)的坝体开始下沉。
凌晨2时20分,郭某再次上坝检查时,发现尾矿库西北段坝体溃塌,立刻向调度员李某报告,李某立即向车间主任张某报告。事故发生后,当地市政府第一时间启动应急响应。溃口于3月24日实现合拢,开始进入坝面调平加高阶段,基本完成尾砂坝临时处置工程。
事故淹没下游鱼塘近400亩,造成下游居民2人死亡,1人失联。
经事故调查发现:该尾矿库坝体溃坝段底部为采空区,采空区的顶板花岗岩经长期风化侵蚀而坍塌。甲铁矿关于尾矿库管理的安全生产责任制和安全管理制度长期缺失,没有明确管理人员和巡坝人员职责。安全投入不足,没有严格按照规定提取使用安全费用。对坝体的安全监测如位移等监控设施布设间距不符合规定。每年的员工全员培训内容,仅包含劳动防护用品的穿戴。同时安全管理人员和技术人员缺乏,人员配备不足。
根据以上场景,回答下列问题:
【背景资料】
某施工单位承建一山岭重丘区高速公路工程,起讫桩号为K12+200〜K27+700,路基设计宽度为24.5m,纵断面设计示意图如图1-1所示,半填半挖横断面示意图如图1-2所示。其中K12+200〜K15+600段穿越农田,其间经过几条农用灌溉水渠,水渠的平均宽度约3m,渠底淤泥底标高比农田软土底标高平均低约1.7m,渠位均设涵洞,涵底处理依照设计;结合地质情况,农田软土层平均厚度1.25m,最深不超过3m。由于地方交通道路等级较低,农用水田、旱地宝贵,因此合同约定不许外借土石方填筑路基。
施工中发生如下事件:
事件一:施工单位根据全路段原材料情况及K12+200〜K15+600段软土厚度,采用了垫层和浅层处理技术进行软土地基处治。
事件二:在施工准备阶段,施工单位经核对设计文件,发现本合同段路基填方总量约35万m3,最大填方高度4.3m,主要集中在K12+200〜K15+600;路基挖方总量约9.7万m3,主要集中在K18+315〜K21+035,开挖深度0.85m〜15.7m,山体除少量风化表层外均为硬质石灰岩。
事件三:经现场勘查并查阅图纸,发现K20+223〜K20+550为全断面挖方段,最大垂直挖深5.8m,K20+550〜K21+035为半填半挖段,最大挖深15.7 m;为减少征地并能维持路基稳定,在半填段设计了较常用的重力式挡土墙,它主要依靠圬工墙体的(A)抵抗墙后土体的侧向推力。
事件四:两隧道的主要穿越区段均无明显溶洞,岩石为较坚硬石灰岩,岩体较破碎,属于Ⅲ级围岩段。施工单位在修筑填石路堤时,将填方路段划分为四级施工台阶,分别为:在路基面以下(B) m为第一级台阶、(B) m〜1.5m为第二级台阶,1.5m〜(C) m为第三级台阶、(C) m以上为第四级台阶。
事件五:施工单位在本工程路基填筑时采用了自重15t的振动压路机。
