That is irrelevant because there'll be uncertainty after Brexit if it goes ahead; it certainly won't be all sweetness and light overnight. Whatever the cause of a recession it is very damaging to the economy. Here's an example of what could happen in a large company; I did cut and paste this bit because I was losing the will.....
"As sales revenues and profits decline, the manufacturer will cut back on hiring new employees, or freeze hiring entirely. In an effort to cut costs and improve the bottom line, the manufacturer may stop buying new equipment, curtail research and development, and stop new product rollouts (a factor in the growth of revenue and market share). Expenditures for marketing and advertising may also be reduced. These cost-cutting efforts will impact other businesses, both big and small, which provide the goods and services used by the big manufacturer."
