Well, surely there should be some minimum staff numbers on the shift at the hotel so hotel was safe place to stay for residents and also for the staff at the hotel? Would like to know if Law says anything about it?
The law does not specify a minimum number of staff that are required to work in any specific business. This will depend on the type of business, any associated risks and these will of course vary from one business to another, from premise to premise, depending on the size of the business, the needs of the business, etc.
So you cannot say, for example, that a hotel needs a minimum of 10 staff, when that may be sufficient for one place due to its size and needs, but may be way too much for a much smaller venue.
The employer will have a duty to determine what, if any, risks exist and deal with the appropriately. They have a duty to ensure the health and safety of their employees so if that means placing a minimum number of staff at any one time, then they would be expected to do this, unless there is another appropriate method of dealing with these risks.
Please let me know if this has answered your query or if you need me to clarify anything else for you in relation to this?
