They don’t have the contractual spirit, whatever stated in your offer letter, they will change it without informing you. They will say company discretion to change without inform anyone, even if it is against the MOM law.
They will sweet talk you during interview, but change immediately after you step in to the door. MC? AL? Don’t think about it.. they love to find you when you are on holidays, but definitely not when in office.
No Christmas party, No CNY company dinner, no half day off for the eves.. even a piece of tissue, any benefits or privilege towards to the employees will cost the company great fortune.
Do not fall for the 5 stars review, if it is that good, there won’t be people resigning every month.
