Yes, if there is a contractual right to do so. Furloughed employees who start work with another employer during this time must inform HMRC that they have another job.

The guidance from the Government concerning private sector organisations is very different from the guidance for public sector and organisations that receive public funding. The guidance states:

“The government expects that the scheme will not be used by many public sector organisations, as the majority of public sector employees are continuing to provide essential public services or contribute to the response to the coronavirus outbreak.

Where employers receive public funding for staff costs, and that funding is continuing, we expect employers to use that money to continue to pay staff in the usual fashion – and correspondingly not furlough them. This also applies to non-public sector employers who receive public funding for staff costs. Organisations who are receiving public funding specifically to provide services necessary to respond to Covid-19 are not expected to furlough staff.”

This guidance isn’t particularly clear but it appears that there is a recognition that there are different types of organisations which could be caught by this:

1. Organisations who will be required to provide frontline services during the Covid-19 response. It is interpreted that NHS organisations such as NHS Trusts will fall firmly into this category. Employees of such organisations are expected not to be furloughed and to continue to work and be paid their normal salary in the usual way.
2. Organisations who receive public funding to provide services to respond to the Covid-19 crisis. These organisations are not expected to furlough their staff. The type of organisation that would fit into this category are those that have been commissioned to developing breathing apparatus or testing kits to meet the needs of the healthcare sector during the peak of the pandemic.
3. Organisations who receive public funds for staff costs to operate services. Employers are expected to continue to pay staff if the money to pay them is publicly funded. It is strongly inferred that this is irrespective of whether such staff have any work to perform. The type of organisation that is likely to fall into this category are GP practices, charities and private sector companies that have won contracts with the public sector.

Employees who are union or non-union representatives may undertake duties and activities for the purpose of individual or collective representation of employees or other workers. However in doing this, they must not provide services to or generate revenue for, or on behalf of your organisation or a linked or associated organisation.

Employees who are pension scheme trustees or trustee directors of a corporate trustee may also undertake trustee duties in relation to the pension scheme. However, a professional, independent pension scheme trustee who has been furloughed by the independent trustee company cannot undertake trustee work that would provide services to or generate revenue for, or on behalf of, the independent trustee company or any organisation linked or associated with that independent trustee company during hours when they are recorded as being on furlough.

Yes, this is very likely to amount to a reasonable management instruction which is put in place for public health reasons. Employers should make it clear to their employees that this is something they are required to do and that if they fail to do so this may lead to disciplinary action.
