So you know a thing or two about them, you think that brexit can be a problem for them?
Massive problem and on many levels. Unilever trades on London Stock Exchange. The sudden and unplanned for low value of £ impacts everything:
its raw material costs dramatically increase hence trying to force through price hikes to uk consumers.
Employing people in UK is now relatively more expensive. Eg: It would be cheaper to have many key executive posts based in Asia or even the US right now.
Cost of R&D within UK will increase dramatically. I'd imagine they willl divert more and more projects to their research centres in Netherlands, India and China.
Even cost of things like advertising production make no sense in UK when similar competence can be found outside.
In terms of free movement of European staff, that will massively reduce as BREXIT employment rules change. That reduction in cultural diversity and movement of human intellectual capital will also make costs increase. Also I'm sure EU membership allowed for UK manufacturing incentives which will now disappear and so make it unattractive to have those factories in UK.
For truly multinational British firms like Unilever, Shell and others, BrExit equates to a potential 2% impact on margins. The Only way to offset that is to take costs out of UK (fewer jobs) and pass on to the consumer.
Also indicative of the lunacy of BrExit: Unilever spent 20 years honing it's European supply chain and organisational structure to benefit from the EU. They now suddenly have to undo everything because some stupid idiots 'wanted their country back'. BrExit voters said they wanted to send a shock to Westminster. Well while the politicos faff around, the private sector has to do all the uncomfortable adjustment and UK people will end up losing whatever happens.
Scarily for me, this tesco/Unilever fall out is a microism of the entire impact on UK economy.
