HIV and employment

To anyone here in the Philippines, I just want to know what's out there.

Have you heard of or witnessed any incident of employment regarding HIV condition? Among others, but not limited to:

a.) denial of work promotion due to his/her condition
b.) enforced work demotion due to his/her condition
c.) denial of medical procedure and/or hospital admission by an insurance company in line with HIV-related medication
d.) mandatory HIV testing for pre-employment
e.) continuous non-remittance of the employer of Philhealth contributions (this is pretty much a perennial problem)

Or perhaps, your experience not necessarily listed above that concerned your condition with your present employment.

Names are not needed to be divulged.
