M:I work 9 to 3,then I start again at 5:30 and work until 11

M:I work 9 to 3,then I start again at 5:30 and work until 11,six day a week .So I have to work very unsocial hours.
W:And do you have to work at the weekend?
M:Oh,yes,that is our busiest time.I get Wednesdays off.
这是听力对话的一部分.第一行第一句I work 9 to 3中,work与9 to 3之间为什么没有词,还是9 to 3作work的宾语,那这样的话该怎么翻译?在work work very unsocial hours中也是这种情况,work后面的very unsocial hours作状语还是宾语?还有一个问题,就是最后一句话I get Wednesdays off中的off在句中作的什么成分?
