Nowadays, some women work full time, some part time, and some seek creative solutions such as flex-time work schedules and job sharing. Many are single mothers raising children by themselves. But in most cases, one income in the household is simply not enough, so both parents must work to support the family.

如今，一些婦女全職工作，有的兼職，有的尋求創新的解決方案，如彈性時間工作時間和工作分擔。很多是單身母親獨自撫養孩子。但在大多數情況下，在家庭一份收入根本不夠，所以父母必須工作來養家。
