Remote working might reduce office costs, but on the other hand, the demand for various collaboration tools increases so that these people can do the job in an optimal way.
Remote professionals need the right tools to communicate and collaborate, share notes and sensitive credentials, arrange meetings and video calls, submit a request to go on vacations, and so on.
Such tools and services might have been considered nice-to-have ones some years ago, but now they are absolutely must-have ones so that a remote team can function smoothly.
