Each employer irrespective whether they may be a Voluntary organisation, private company or public service has a duty of care to provide for a safe working environment under Health & Safety Law. Whether the employer is a voluntary management committee or if these people on the management committee have low levels knowledge of their legal obligations as employers is no justifiable excuse when it comes to non-compliance with health and safety law. Equally, lack of funds is no excuse. Has the employer conducted a risk assessment of the working environment identifying potential hazards, and is there a safety statement - this is the law in respect to all workplaces?
Do you have a grievance policy in the workplace that sets out the procedures that you can follow in order to bring your concerns to the attention of say your next in line manager? Also, it may help if you are a member of a trade union - but in my experience you would have to press the union to act on these kind of matters. If your concerns are not addressed by the employer - you are quite in your rights to report the employer to the Health & Safety Authority - you cannot be sacked for doing this.
My advice is also to keep a documented record of all communications with your employer especially when you are bringing your concerns to their attention - and do so in writing.
