Help please do i have a case for a tribunal?

my boss verbally warned me about emailing my wife whilst she had been addmitted to hospital with an internal bleed following the birth of our twins. i did not email her again and now i feel i am being bullied to resign. he told me he is only keeping me at work as i have new twins. he is verbally screaming and told me that i am a misfit...this verbal abuse is happening daily. do i have a case for this? i have never had any problems in a job and i am doing exactly what he asks and then he tells me its wrong..its a game. the company are very big and i am still on probation.
