Unless it's the initial outreach team or on-premises staff, sales would be one of the few roles totally suited to remote working.
Some of the more creative or collaborative roles I can see the argument for hybrid working - even if it's just one day a week or month in the office - but sales, customer service, or first line support seems to be the last area you'd impose a return to work mandate on.
That said, I haven't got extortionate office rents to justify π
This is how you get shot for the silliest of reasons.
