I think you need to seach online for some legal advice if taping some of their conversations is permissible then just have a small tape recorder on or about your person and get it translated later and provide a transcript of the conversations they have at your disciplinary.
Women can be a bit funny in a workplace environment (no offence ladies) me and my missus are going to be moving soon and I'm a bit worried about how she'll be recieved in a new job by the women there cos you lot can be a pain to other women if they are prettier or better liked than yourselves... Sorry for the rant but I've worked in the midst of ******** women, all telling me crap about the other women that I didn't want to know and then I watch them pretend to be best mates 5mins later and they'd worked together for 10 yrs!
