Usefully, the Chartered Institute of Personnel and Development ('CIPD') has published practical guidance on hybrid working. CIPD: Hybrid Working Practical Guidance (3 December 2021)
The guidance suggests that you:
define hybrid working in your business
consider your strategic goals
decide how to effectively recruit and manage hybrid workers
ensure that your hybrid working policies and practice are inclusive to avoid any unintended consequences.
train your managers to manage hybrid teams and support hybrid workers
continue to listen to your employees as they describe their experiences
remember that hybrid working is still evolving so adopt a flexible approach.
