日前，广州媒体“卧底”曝光麦当劳、肯德基等洋快餐店违规用工，其钟点工的工资低于非全日制职工最低小时工资标准。此外，洋快餐连锁店还被指控犯有“不为兼职工缴纳工伤保险、故意延长兼职工试用期”等六宗罪。
请看China daily相关报道：A popular local newspaper claimed that the US fast-food giants are violating Chinas labor laws by under-paying part-time workers by up to 40 per cent in their local chains.
"The fast-food chains have also asked the part-timers to work longer than the maximum five hours a day, deliberately refused to sign labor contracts or insure them against workplace injuries, and prolonged their probationary periods."
报道中的“probationary period”就是求职者必须经历的'"试用期"，也可写做“probation period”、“probationary employment period”或“trial period”。
“Probation”在此指“以观后效的查看”，也可和介词“on”连用，表示“在试用期”，如：Well have to take you on one months probation first(我们得先试用你一个月);He is a mechanic on probation(他是个见习机械工)。
此外，probation常用来指“缓刑”，如：three years probation under suspended sentence of one years imprisonment(一年有期徒刑缓刑三年)。
