in short, there isn't any legal recourse for you, unless there is a contractual agreement between the employer and employee to pay out retrenchment benefits, or collective agreement between the employer and trade union. retrenchment benefits are not mandatory in law, although there are local market norms. so working in MNC or SME makes no difference.
in your case, unlikely you can negotiate because MNC will usually have their own rates for payment. you can try your luck and ask for more but usually the budget approval phrase would have been long over by the time you received the retrenchment news. furthermore, if the company is very good and pay you everything plus extra or even go above the market norm; retrenchment benefits, annual wage supplement, performance bonus, salary in lieu of notice, en-cashed annual leave, claims and so on, you will hardly have any room for negotiation.
if you are a union member, you can go to your union and see what they say. your profile in terms of tenure and position or even age may have a positive or negative influence on your case. if you have raised your concern with human resource and reporting manager, that is good enough. at the most, you can try highlighting to your reporting manger's boss. suggest you don't jump the gun, efforts will be best spent on searching for the next job instead.
