What was the termination clause stated in your contract of service with the employer ? Which state of Malaysia are you in ?
If termination clause is not stated then under the Employment (Termination and Lay-off Benefits) Regulations 1980 (Peninsular) the notice shall be as follows : 4 weeks notice - has been employed for elss than 2 years : 6 weeks notice - has been employed for 2 years or more but less than 5 years : or 8 weeks notice - has been employed for 5 years and more.
But it is also possible for employer to terminate the contract of service without notice by paying to the other party in indemnity in lieu of notice, if there is a willful breach by the other party of a condition of the contract of service.
However, an employee is not entitled to termination benefits in the following circumstance : employed for less than 12 months on date of termination or the contract of service is renewed or the employee re-engaged on terms and conditions not less favourable than his previous contract or where the employer has offered to renew the contract on no less favourable terms 7 days before the date of termination, and lastly where after receiving due notice of termination of contract the employee leaves the serivces without employer's prior consent or without paying the employer the indemnity due contract of service.
As for the entitlement - termination/lay-off benefits not less than the following : 1-2 years service - 10 days wages for each year service. More than 2 years but less 5 years service - 15 days wages for each year service. 5 years or more - 20 days wages for each year service. In addition, termination benefits payment shall be paid not later than seven days after the termination.
An employee is only deemed as absent from work without permission and without reasonable excuse only if the employee goes on sick leave without being certified by a doctor or if it is certified by a doctor but fails to inform his employer within 48 hours of the commencement of the sick leave.
It is best you seek advise from the nearest labor department. To lodge a labor complaint normally you need your IC, Letter of appointment/contract of employement, dismissal letter, and provide to them the correct name and address of your employer.
I am not sure whether there is any specific time you should file in your complaint. Usually sixty days from notice.
You can also try firstname.lastname@example.org the Ministry of Human Resources Head office in Kuala Lumpur, Malaysia for confirmation.
Your employer seems to be so mean and deliberate in firing you.
