Linksys 48 port unmanaged switches

Hi, i have scenario where i am looking into a network implementation. There's a 48 port unmanaged switch being used in a network. However, there's more devices and users to be hired, so the local IT person bought another 48 port switch and connected that switch to the current switch to be able to accomodate more users in a different floor.

Isnt this going to create problems? Would this unmanaged switch behave like a regular HUB?They are linksys 48 port switches like i said unmanaged. i am asking because since they are unamanaged, i am not sure how they work. All my experience is with Cisco routers and switches. I know an unmanaged switch cannot compare to a Cisco managed switch.

Any ideas?
