So, help me. DH has been sacked. He's had some issues with one of the managers were he works lately. She's a bit up herself and humiliated DH in front of everyone at work by shouting at him for simply using a nice word towards her. People heard it and was shocked. DH puta grievance in after this incident and as if by magic the grievance disappeared off the system. A few days later DH vented his frustrations to his work mates at work and on the same day one of them went to Another manager and made accusations against DH that would suggest he used discrimatory words. DH denies this. They suspended DH immediately. They then didn't interview any witnesses until the next day. All the witnesses sit close together and are friends outside of the work place so could have communicated. The next day at interviews. Two of the witnesses said similar stories but not exactly the same and the one who made the accusation in the first place quoted DH but in the same sentence said she couldn't be sure what his exact words were. They also got statement from others about DH general mood of late at work. DH had asked them to look into the grievance he had made to which it had gone and he also asked them to ask a witness about one of the managers humiliating him that time. They didn't get any witness statements from anyone asked. They sacked him a couple of weeks later based on gross misconduct and also said They had to sack him anyway as they couldn't put him back in the same room as his accusers.
My question is do we have good grounds to appeal?
