Question: Senior management at my company are talking about possibly introducing hot desking\*, which might be introduced at the same time as an office move planned in a few months. The new location will be large enough to accommodate the company size; there will be enough desks for everyone, space is not a problem.

What problems does hot desking strive to solve, apart from not having enough desks?

Does it actually solve those problems?

\*From [Wikipedia](https://en.wikipedia.org/wiki/Hot_desking): *"Hot desking is an office organization system which involves multiple workers using a single physical work station or surface during different time periods. The "desk" in the name refers to an office desk being shared by multiple office workers on different shifts as opposed to each staff member having their own personal desk."*

Etiquette is: I select only one answer, but several answers here answer this question; there are several other excellent answers.

Answer: 
Hotdesking doesn't solve any problems, no matter whether the office is too small or not.

I've worked at a company that had 20-40% fewer seats than employees. Battles for chairs cost us (and company...) plenty of time. It was a drama. The most important part of the day was ensuring you had a chair.

Your company is probably expecting to grow. This could explain why they want to introduce the system now.

Or maybe they just want people to "network more". But that's not the way to achieve that.
As others have already said, it solves little if any problems, but there is one situation that I have experienced where at least can be helpful.

That is the 24/7 business. Any business which has people in the offices 24/7, i.e. upto 3x8hr shifts. This is common in a call centre environment, but can also exist in other environments too, depending on the company.

I can't tell you if your company is thinking to use this or not, but it's an 'advantage' of hot desking - as long as you only ever have 1/3rd of your total workforce working, you only ever need desks for 1/3rd too.
