To think you should be told why you're being suspended?

[Freight]

Posting for a friend.

She has been advised that a formal complaint has been made against her by a member of a team she is newly managing. They would not tell her the basis of the complaint but have suspended her on full pay pending the outcome of an investigation. She has been told she will find out what the complaint is next week and then a meeting will be held two days later and in the meantime she is not to contact any colleagues. My friend has no idea what this could be about.

Do they have to tell her what the basis of the complaint is? What should she do?

Suspension is 'informal' and is a means of mitigating risk to the organisation - whether that risk is a violent person being in the business or their presence impacting an investigation. Yes it's best practice to tell them why they are suspended but it's not the end of the world procedurally or if they can justify it.
