<human>: Hi 
I work in call center for a big company in Ireland.  

I am there 3 months when I had an accident in work where the chair I sat into fell apart and I have been out of work without pay for the last 3 weeks. The company I work for has a no payment for injury or sickness policy.  

I went to my union and my union wants witness reports from people who seen it.  

My co workers were all for seeing how I was and telling me to let them know if I needed anything. When it came to putting their accounts into writing they don't reply.  

I can understand they are afraid of anything that might come of it as we are all within our 6 month probation period.  

I just can't help about feeling resentment towards them as they are stopping me from moving forward and without witness reports the case loses much of its pushing power.  

I feel like I will be angry with them when I do get back to work and it will sour friendships that I have made.

Does anyone have any advice on how to deal with this?

Could you distill the essence of the text into 1-3 sentences?
