“To Whom It May Concern, I wish to inform you that myself and Christopher Alan Thomas have resigned from British Gas. I resigned 4 September; Mr Alan Thomas resigned July 23 rd . We believed we have been constructively dismissed from the company in addition to being unfairly dismissed from our outbound energy sales role. We believe the situation we’ve been put in by the company left us with no reasonable option other than to resign. [Then he produces a copy of the resignation email]. I‘ve given reasons why I believe that I’ve been constructively dismissed by the company in addition to being unfairly dismissed from my outbound energy sales role. Both myself and Christopher Alan Thomas wish to amend our claim to include constructive dismissal in addition to our claim of unfair dismissal of our outbound energy sales role.”
