Engineers are the life blood of any service based business, and Briggs is not exempt from this, so they need to be treated with the respect they are due. That said, Briggs are running a commercial business and it's a competitive market out there. Any business needs to ensure they are maximising commercial value from every employee. My understanding is that any proposed T&Cs changes are based on rewarding those that perform well and not rewarding as well those that don't. As a principle, that's not unfair is it??
