I'm not a lawyer. AND I do recommend you consult with one. The following is a suggestion you might want to discuss. Based on your contract, you should be able to get an enforceable demand for your employer to pay you. If you are not paid and the deadline for payment expires, you might be able to get a lien over the server and other property. At that stage you can shut things down, etc. If the employer is a company then there might be a case for flagging them as trading whilst insolvent. Under UK law that is a biggie. As @issa suggests maintain your dignity and professionalism. Taking revenge could put a dark cloud above your reputation. Unless you have political skillz be very careful with how and with what you contact board members. They might be in cahoots with your problem person. I'd suggest in person meeting so you can better assess the situation. Emails are often very unsuitable for such information.
