Employers CANNOT reject employees' resignation letters.
Likewise, if employers terminate employees, they (employees) cannot
heck care and work on.
It is best to submit your resignation letter to your boss and cc to
his/her boss.
If you have any problems about getting your pay after your one
month's notification period is over and you've fulfilled the one
month's job minus any outstanding leave due to you, report to
MOM.
Resignation Letter (Sample)
XYZ Company
Address
Att : Boss's name in full
His Designation
RE:
RESIGNATION
Dear Mr/Miss/Mrs or Mdm Boss's surname,
I hereby submit my resignation with effect from (today's
date).
As I have x number of leave due to me, my last day of employment
will be
00th month, year.
(Cite reason - if you REALLY want to resign). If the true reason is
becos of your boss's attitude you cannot say so. He/She can make
your last month a living hell and if u leave b4 your one month's
notice, then YOU have to pay the company one month. Best to cite a
reason that your boss cannot stop you from leaving. For e.g., going
for full-time studies; migrating overseas; relative needs your help
with his/her biz immediately; need a long break to regroup and
destress as recommended by yr doctor 
If you do not cite a reason, your boss might think you do not have
a plausible reason to leave. Some bosses know it's hard to find
workers so they will psycho and psycho their staff to stay.
Thank you
Yours sincerely,
Si Bey Sianz
