I left in March 2018 - 9 months on, I am earning more, sleeping better, stressing less and loving life..... BTW I am 58 and have found some significant contractor opportunities exploiting my 30 years of experience in IT which make is a pleasure to get out of bed in the morning....
A lot of what I do as a consultant is to fill the gaps created by the "bright young things" who cannot function without a mobile phone in one hand and a tablet in the other.....
