Brexit: are you communicating with your non-U.K. workforce?

Recent research by @totaljobs and published by @HRReview points towards high levels of anxiety by non-U.K. employees ahead of the referendum vote on June 23rd. In the event of a vote to Brexit, many fear for their medium term job security. 

For me, the statistic that jumps out is the number of employers who have not undertaken any proactive communication with their non-U.K. workforce. Which camp do you fall into, communicator or non communicator?
