I mean, it’s not really a “in office” v “remote working” debate - people will slack off and make themselves look busy regardless of where they are. That’s caused by a case-specific mix of motivation, discipline, or other factors. That’s a line management issue rather than a work location issue - WfH just gets scapegoated for that.
Ultimately it will be the money starting to talk - if the accountants start complaining about expensive office space not being used to its maximum, then they’ll start instructing folk back to the office. It’s a shit reason but unless your contract specifically says remote, it’ll be the balance sheet making the decision for you (edit: unless it really doesn’t work for you and you go nuclear with the “resign” button of course)
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 😂
