If people had a Contract of Employment which had Terms and Conditions in it then possibly yes....you might have a case.
I doubt, however, if MD ever produced such a thing or if he did it was made up rubbish and not worth the paper it was written on........probably bog paper at that.
What concerns me now is that some good qualified people with families, bills to pay, mortgages etc etc may be working their notice period with a decent reputable company thinking that Unique has something to offer. Beware..........MD has nothing but lies....
