I never said it's against the law to work for two employers in China.All I said was that it's DISHONEST to sign a contract with the employer who brought you here in the first place if you break a clause in the contract that stipulates:
a)you request permission to take a second job.
or
b)you cannot take one.

I'd reckon that a) would result in a refusal more often than not.

Another poster brought the PSB into the argument,not me.I'd reckon they wouldn't care about that.That other poster's university was just trying to put 'the frighteners' on the FT's to stop them seeking additional work,so I reckon.
