All's well that ends well I say. She is now able to go off and have her baby assisted by an undisclosed wedge from Easyjet. Even better in view of the fact that she has a nut allergy and no longer needs to work for a bunch of nuts.
What the hell would have been wrong with a written warning to personally emphasise the policy instead of sacking her requiring the recruitment and training of a replacement which will no doubt cost marginally more than an easyjet bacon butty.
