Why are some Filipinos discriminating CC agens who has wrong grammar?

Well, I'm not a cc agent as well but having a good command of the English grammar is a very sensitive issue in my line of work. People don't actually discriminate people who is "grammatically-challenged". We just want to imply that if you're going to do something (re in Filipino: gagaya rin lang naman) then do it as correctly as possible. If you can't do it, then at least try to acknowledge to mistake when presented and treat it as constructive critism. The problem with most Filipinos is that when it comes to criticism, we tend to over-react and feel that those who criticize wants to bring us down and we start shouting "crab-mentality", discrimination, arrogance. etc. And if you are already aware that you can't speak or write in correct English grammar (or any foreign language, for that matter), then you might as well use our own language which is, FYI, a very beautiful and colorful language.

I'm so sad about this why there some other people making fun of us if we don't speak English very well. I'm not working in a call center because why English is not good. I hope that they would understand our situation that English is not our first language so it is difficult for us to perfectly speak it. Discrimination is always been there, some customers are so airy because they can speak english very well.

It is wrong to discriminate people with wrong grammar. But when we talk about it in the call center industry, it is very crucial to have perfect grammar and accent. I guess the reason for this is because there are some American customers who prefer talking to American representatives than foreign ones. There are even those who would actually discriminate you when they hear that you have a foreign accent.
