Supposing the manager of the department has been very ruthless to the fellow colleagues.
What if we report it to the VP of the department, HR Director and maybe even CEO?
This kind of reporting is dependent on your understanding of the business politics in the org. Usually, for MNCs here, all kinds of unthinkable shits are condoned. Mountains high emperor far. MNCs are in Singapore not because of the marketing BS of Singapore being efficient with hardworking and intelligent purposes. It is for tax avoidance purposes. Because the Lees have made this place too expensive, US MNCs have moved a lot of operations to the Philippines, which is a total joke, not because the people are dumber but compliance - the holy word in MNCs - is non-existent. I have witnessed cases where all are in cahoots. CEO sometimes know but condones as the business objectives are still achieved. Whistleblowing and creating uncertainty for a more ideal world may whack overall company performance. Look at our Leemasek Holdings - you tell me.
BTW, Singaporeans are the gongkia that take compliance seriously burning their nights and weekends to achieve a pat on the back. Filipinos and other races, even including ang mohs here who are not management? What do you think?
