when you and your new employer have different ideas

I've often wondered what happens when a high-level marketer with certain principles joins another organisation, which historically, doesn't share those same beliefs.

As a sporting analogy, it's a bit like Neil Warnock (who one could argue has a long-ball approach to football) taking over at Manchester City (where Pep Guardiola has spent the last few years getting the team to play one/two-touch football all over the pitch). 

The objective of winning games may be the same, but their two approaches are opposites.

Would Warnock stick to his tactical guns and say, 'You know the type of football I like to play, and if you want me to be City manager that's what you're getting'? 

Or would he say, 'You're employing me to be the manager of your club, you've got a history of playing a certain way, and I'm happy to adapt my approach accordingly'?

But what happens with marketing and the bus industry? 

If you follow the local branding approach with your marketing and move to a company that goes with a 'one brand' model - or vice versa - what's the outcome? 

Do you try and convince your new employer of your historic success with local branding, and expect them to change strategy to suit? Or do you sit back, respecting their marketing history and all it's achieved?

Guess that depends on both employer and employee.
