Sounds like an episode of all in the family I watched last night. Archie bunker thought he was clever too.Some employers (and managers) aren't that clever either. One of my wives former GM's was a local hire.... they usually bring in overseas people for that role as the NZ market isn't that large so if they stuff it up, it doesn't really matter to a Fortune 100 company.
Anyway, this guy thought he'd be clever when it came to negotiting his contract and didn't read fully what was being offered to him. So, he took what was going to be his starting salary and reduced it if they would do things like giving him a four week notice time instead of eight weeks, a monthly allowance instead of a company car and upgrades to business class for flights over a certain distance. The HR person representing the company quickly agreed to everything including the salary reduction.
It was only after he started, he compared his contract to the company's original offer and found those things were already in their offer when a staff member leaving only gave four weeks notice and the GM was informed that was the companies standard practice. Not that the reduction in salary mattered..... he was gone within three months anyway. Last we saw, he's a manager in NZTA.... heaven help us all!!!!
