If you provide an employee assistance programme (EAP) remember to promote this service regularly, so your staff know they can reach out for confidential counselling and support from trained professionals. 

If you don't offer EAP, then make sure that you and your staff know what assistance is available in the local area or nationally. Consider producing a list of useful numbers, but remember you'll need to keep it up-to-date. The Sheffield Mental Health Guide is a useful directory of  mental health services, activities and resources.

If you have a Workplace Mental Health Champion or a Mental Health First Aider, put posters up in staff areas so that employees can see your commitment to their wellbeing. Replace them regularly, so they don't end up looking dog-eared and neglected.
