We recently regrettably had to terminate one of our employees contracts for gross misconduct.
Since this happened, the ex employee is threatening to show our clients a copy of the internal communications regarding them, ie them being somewhat difficult to deal with however probably wasn't worded as nicely.
Is there anything the company can do to prevent this from occurring? We cannot be held to random for terminating a contract due to the employees poor behaviour, yet also can't risk losing the client.
Have tried to contact ACAS but they aren't open until Monday morning
