I have worked in a forgein company for 2 years,because of my right major and hard-working,my boss has a very high opinion of me.But not long ago,in a negotiation with foreigners,because of the "third party",something unpleasant happened.Subsequently,my boss didn't ask me anything and scolded me extremely angrily.I am very dissatisfied with his practice,but I don't know should I be obedient to the criticization of the boss or I should find some time to communicate with him? Friends,I am very confused,Could you give me some suggestions? Thanks!
