If you are thinking about making a claim to an emplo yment tribunal, yo u should ge t help straight aw a y from one of the anisations listed under Further help. ation about dismissal and unfair dismissal, see Dismissal. You can make a claim to an emplo yment tribunal, even if you haven39。t appealed against the disciplinar y action your emplo yer has taken against you. How ever, if you w in your case, the tribunal may reduce an y pensation aw arded to you as a result of your failure to appeal.
