If we talk about health or insurance benefits, my knowledge about all these is very minimal, or worst, less than that. I really don’t know how SSDI benefits are claimed.
I don’t even know how much SSS contribution I am paying each month. Sure that reflects in the payslip but I am not the type of employee who keeps and tracks of his/her payslips.
Let’s say I so trust our Accounting Department that whatever is reflected there is correct unless the figures are so unacceptable. That’s the time I’d react and question how it is computed.
