If your job exposes you to your respiratory sensitiser or your triggers, then the answer is almost certainly yes. Your chances of recovery are much better if your exposure to the respiratory sensitiser stops within one year of you first getting symptoms. Your employer should try to help you by eliminating or substituting the respiratory sensitisers. If this is not possible they should change the way you work so you can carry on without further exposure. In some workplaces, such as shops, offices or hotels, your local council's Environmental Health Office will provide the same service.
Trade unions can often give information and support.
Your union will probably have safety reps with legal powers to check that you are being protected.
