回复：我是contractor,和A中介签了1年的合同

现在在B公司上班。很大可能会被B公司转成正式员工，但不知是否只能是1年以后。
-- This depends on the contract between A and B.

我现在嫌工资低，不知道能否要求A公司加薪。
-- Yes, you always can ask more salary.
-- But, you may not get it.

我如果辞职的话，A公司就得不到佣金了吧。
-- Why quit your job? Don't do it.
-- A may have contrat with B that B can't hire you within N month(year) after you keft A.
 

我能辞职吗？
-- 胡 says you can't quit job, 胡 is  胡说之。
