the CEO of the company i work with currently plans to close down my advertising media sales department (of which i am HOD) because a third party company is talking to him to buy over the inventory. Furthermore, as HOD, i was never roped in for these discussions. Therefore, the positions for my teammates and i will be redundant and not required. We are given the option of trying to apply for other opportunities in other department / sister companies, but doing different things which we are not familiar with. We are being pushed to a corner without prior notice and consultation. If we decide to resign (constructive dismissal) and not take up any offer they might give to us within the group of companies, do we have a strong case if we want to seek compensation? Our salaries per month exceed RM5K per person. Who should we speak to who can advice us on what our plans of action are?
