i think the best way is to have a meeting with your manager and the filipino involve in that way you know what's the main issue/problem was.
like you i am trying to distance my self with my co-filipino in terms of work i am working with a filipino on the same shift every other night which is better than every night. i agree with you that filipino carers are the best.
my unit manager is the best for me, she is strict but she is always on our side if problem arises. she is always there to depend us specially to our horrible matron. well, i'd been to a few troubles at work (wrong accusation or being pick) but i know how to depend myself specially if i didn't do anything wrong at all. some of my colleagues think i am a fighter but sometimes you have to be bec if they think you're weak they'll just pick on you.
hope things will okay. good luck
