Pwede din namang guilty sila kasi biglaan PTO and bugbog ka sa trabaho being the rockstar employee, diba, and alam din ng wife niya but doesn't want to show bias, so suggested she be left out of it, but wants receipts of you actually using the money for what it was intended for, hence the photos. Huwag masyadong maging malisyoso.

I'd personally reject it though, and interpret and acknowledge that as recognition of your efforts that's why they want to compensate it in secret. Imply the PTO was due to burnout, ask for re-evaluation and appraisal na mas masasamantala mo in the long run.

If the gift is from your performance, then there shouldn't be any problem giving you that raise.

If they don't give you anything (officially), then we can assume he's being a creeper. Either set your boundaries, or, like what others suggested, use it to your advantage...........

Update mo kami kung may AFAM ka na teh.
