If, after deploying all control measures the risk is still deemed too great for employees to work safely, then what should employers do?

Yes.

An employer which is aware that a worker or agency worker is or ought to be self-isolating, should not knowingly allow that worker or agency worker to leave the place that they are self-isolating in (“the designated place”).  To do so without reasonable excuse would amount to an offence which could result in the employer being issued with a fixed penalty notice.

The value of the fixed penalty varies depending on if it is the first or subsequent fixed penalty notice to be issued:

Yes. With respect to employees you have an obligation to protect their health so you can gather information to do that. You might gather information from your employees on who has the virus, who has had it and recovered and also who has tested negative. You might also want to know if individuals have been in contact with someone who has it or if they are in a vulnerable group. It is reasonable to want to know where individuals have travelled. In the future it may also be reasonable to know if they are planning to travel to a virus hot spot, as the impact of the virus around the world is likely to continue for some time even after the outbreak has been contained in the UK.

It is reasonable to gather some information about visitors to your site, be they customers or suppliers, as this information will also help protect your staff. However, you should keep what you gather to a minimum. For visitors, it’s unlikely that you need to know anything more than they have Covid-19, are displaying symptoms or have recently been in contact with someone who has the virus.

Maintenance Orders embodied in a Court Order are variable. If you have lost a very large part of your income, then the Courts ought to take that into consideration when looking at a Court Application to reduce or end spousal maintenance payments. The outcome of any Court Application will, however, depend on a number of factors.

Technically, you should not just stop paying or reduce the maintenance payments, as your ex-spouse could then make an Application to Court for enforcement and payment of the arrears. You could ask the Court to forego you having to pay those arrears if you had evidence to prove that you could not make the payments, however, the Court will need to take a fair approach and you should not assume this request will be agreed.

You should first try to negotiate a reduction or termination of the maintenance with your ex-spouse, either directly or through a Solicitor. If this is possible, you should obtain a Court Order reflecting that agreement. Where a sensible compromise cannot be reached, a Court Application may be necessary.

The government has produced a series of industry specific “Covid-19 Secure” guidelines, which employers should follow. These guidelines are designed to keep the risk of infection as low as possible, while allowing as many people as possible to resume their livelihoods.

Conduct risk assessments! Your RA must cover every foreseeable risk arising from a return to the workplace, including the impact of reduced staff levels and any operational/administrative changes necessary to ensure social distancing.

Appropriate steps should be taken to manage and mitigate identified risks. Where this is not possible, businesses need to decide whether certain activities are necessary for the business to operate or if they can be temporarily put on hold.
Keep a close eye on the comprehensive Government guidance: https://www.gov.uk/guidance/working-safely-during-coronavirus-covid-19

In particular focus on social distancing and workplace health measures. This guidance will evolve over time and you will need to be sure that your organisation is sticking to it AND reviewing and updating its risk assessment.
