I work for a security company and they are suspending me because I am the managing director of my own security company I have worked for them for 3 years and they do not have a reason other than I have my own security company can they do this and what can I do about this I have only started my company up in the last 3 months can they do this they said I'm suspended until this matter is resolved so basically until I stop setting my company up the directors of the company have said they need to get rid of me asap any help. All of there work is based in Lancaster they have 4 doors in manchester I have worked on the same door for the past 3 years I do not go to venue to venue or job to job where I can speak to there clients.

You can't seriously expect them to pay you to go out and work with their customers long enough for you to talk them into moving their business to your company. Of course they can, and should, terminate you. There isn't a business in the world stupid enough to put their competitors on the payroll. :-)
