You'd hope so. I noted there was no mention of WTR which would be relevant. It's an interesting point - we've moved from managing people via hours worked to managing via outputs, but what if they can do their outputs in less than a full working week. Do we have a right to the rest of their time or if we are getting the right amount of work out of them for the salary we are paying them, can they reasonably spend the rest of their time doing something else?
I would like to say No but as very few employers would say yes then providing no damage is done, why would an employee ask?
if they get dismissed they just carry on with the other job and maybe try for another one.
