Employment tribunal

[gabciu]

Hello, I have a bit of situation here. I used to work in a bar owned by private owners. The whole place was just a big mess. For a long time they do not provide any contracts, make people to work very long shifts (up to 16h sometimes) and without any breaks. Even during restrictions, they were breaking all the rules so they could make as much money as they could. They tried to avoid paying tax for staff, didn't pay pension, to avoid tax from money they earned during weekends, they just didn't put them on the system, but they were taking cash and putting on the side and etc. So I'm taking them to tribunal for such issues, but the problem is that people who decided to write witness statements are scared that their identities will be disclosed. And also as my identity is already clear to them, they are known in the city as very rich and powerful owners. They deal with gangs, criminals and drug dealers. They can pay off licencing or maybe even police. Could anyone help me out with the claim to the tribunal? And also, without any sugar coating and just saying that it can be illegal to happen - is there a chance that I'm putting myself in situation where I might end up being hurt or not getting help from the police? What would happen if they would pay off the witnesses from inside? Thank you
