[20] Are flexible working arrangements for women with children causing resentment among those who don't have children? Researchers in Britain have found that many of those surveyed thought women who worked flexible hours were less committed than their colleagues.
[20] Working part-time, leaving early to pick up the kids: flexible working is seen as something that can help parents, but it could be having a negative impact.25,000 women were surveyed. About half of those questioned said that women who worked flexible hours were resented and viewed as less committed by their
colleagues. Here is what some people surveyed in London thought.
"There is some resentment definitely. [21] I think it's more a case of like with younger people in their 20s. They do kind of look at some of my older colleagues and sort of saying  ' well, it's not really that fair.' But I think they might change their tune when they are perhaps in their 30s and when they are thinking about kids." "My colleague, when I was leaving some part-time, mouthed  ' I hate you'. And I think that was because I do manage to strike a balance.""I passed from 95 jobs, full-time to freelance."  "And so it's not just women with children that want that flexibility?" Jody Day, who founded the organization Gateway Women for women without children, said they had legitimate reasons to be resentful. "It's a difficult issue to bring up in the workplace because it's actually about fairness and equality, and diversity. And if most of the women in the office do have children, there is a sense
that's a kind of dominant sort of group think. And it can be quite difficult to get your voice heard if you are the childless one in that situation."
"Managers are often confused about what fights and privileges people have because they are trying to do the fight thing. They are worried about what the law says." [22] The researchers found that the negative judgment attached to flexible working could be an obstacle to women's progression. They've called on businesses to do more to change that.
Why do some women employees work flexible hours?
【解题思路】四项均以because开头，可知本题考查原因，需特别注意因果关系处。听录音时应将重点放在四项的关键信息上(unsatisfied with their work，take care of their children，companies with loose management，don ’t take their work seriously)。
【解析】讲座开头部分提出问题，有孩子的女员工会因弹性工作时间安排而引起没有孩子的员工的不满吗?接着提及了一项调查，然后说道，非全时工作，早退接孩子 ——人们认为弹性工作制能够帮助有孩子的父母，但是这也可能造成负面的影响。可知实行弹性工作制是因为这些女员工需要照顾孩子．故B项为正确答案。A、C两项在讲座中未提及，可排除；讲座中提到调查结果显示工作时间灵活的女性不如她们的同事对工作更投入，但这并不是实行弹性工作时间的原因，D项不符合题意，也应排除。
