Hi Rochelle – I would not take the risk of the cultures are not compatible. I think mergers are hard enough when there is a similar culture.
For example, two company’s could have a very similar culture with regards to customer service. However, how Company A might view customer service versus how Company B views it might be very different. It’s the ‘how to handle it upon merger’ that could cause issues. Similar company’s would most likely give the other the benefit of the doubt and collaborate.
Incompatable cultures would not work easily together to find a solution.
