I am british, and can only speak english.
For the past 3 years i have worked in a team of 3 including myself and 2 polish women who can speak english fluently. During which time the ammount of english spoken has reduced to nil.
Being uncomfortable excluded form the team i asked them if they could only speak english. They were uncomfortable with this, accused me of being racist, and proceided to try to make my working life as uncomfortable as possable and turned the wider team against me. To the extent that i got HR got involved. This exacerbated the situation and there where several incidents as a result, where i was accused of god knows what to my manager. I took audio recordings of some of the taunting but i was informed i would get fired if i showed them to my manager. My manager has threatened to undergo disaplinary action should the conflict continue.
I am on a final written warning for a previous incident where i got angy. These women are aware of this and try to anger me so i get fired. They are manipulative and im confident they will accuse me of being aggrressive (whether i am or not) and a racist should disaplinary action continue.
What advice can you give me. Do i have the right to demand they speak english in the first place? How can i prove that im not racist or aggressive when its one word against anouther?
