Sub Contractors have the same responsibility to their employees and to persons who may be affected by their work as Contractors do. Contractors must supervise their sub contractors.
Health and Safety Responsibilities for Sole Proprietors and the Self Employed
Where the employer is a self-employed person or a sole proprietor, then that person is clearly the one who will be held responsible for ensuring that the legal duties have been fulfilled.
It is vital that if you do not feel up to discharging these responsibilities yourself, that you appoint a competent person to help you straight away.
If you do not you are already breaking the law.
Health and Safety Responsibilities for Partnerships and Companies
Where the employer is a partnership, every partner is responsible. Where the employer is a company, every director is responsible.
In the case a partnership or a company, if no one is given day-to-day responsibility on behalf of all of the partners or directors, then every single partner or director must personally ensure that the day-to-day responsibilities under the law are being discharged.
The Board of Directors or the Partnership Meetings must then supervisor the person given responsibility.
