A certain local big supermarket also had these terms in their
contract
You are obligated to work overtime, on weekends, or on public
holidays if necessary, and you will not be entitled to any
compensation in the form of overtime pay or off-in-lieu
Basically, they wrote into the contract that you are a slave to
them.
I told my friend not to sign the contract, and to specifically
highlight this clause to whack.
The HR said it's just written in for convenience, but its not
really executed.
In that case, why write it in?
Exploitation of labour by our OWN singapore companies.
For your case, maybe write into MOM an email to ask what you
should do, though I suspect they will just tell you to find a
lawyer should that happens. I used to have a clause in my contract,
stating that I am not to work for any rival company that is in the
same business as my ex-company for 2 years, starting from the
effective date of my resignation. But I understand that in court,
this clause is not really enforceable.
