growstuff, in regard to your two above posts, the core legislation for employee safety is the Health & Safety At Work Act 1974.
In regard to employers duty of care, that act states that "it is the duty of every employer to carry out "ALL THAT IS REASONABLY PRACTICAL to ensure the health & safety of all their employees while at their place of work.
What constitutes "all that is reasonably practical" has been the subject of very many court hearings since 1974. However, It is already the case that employees with underlying health issues etc are stating to their employers that they feel it would be unsafe for them to return to work in the present crisis.
In normal circumstances, an employer would request such an employee to attend what is known as an "employment role compatibility review" which would determine whether the worker would, into the future, have the capacity to carry out the job role that he/she is contracted to undertake.
Should it be that review finds that the employee will not be able to carry out that role, then sadly the employer is entitled to dismiss the employee from their employment?
That stated, in the present unprecedented circumstances it is expected that the industrial courts will be making the first landmark rulings on the above issues in the next few weeks. However, that may be followed by the issues being taken to the appeal courts or even the Supreme Court I feel.
There is much to be determined in regard to employment health and safety at present, as we are all in exceptional circumstances in regard to this Covid-19 situation.
