I'm not sure I'm understanding your point. You're saying you're willing to pay an additional ~400EUR/month so you can work for home? Or are you saying $employer should fork out the cash? That's 10% of my net pay, and I'm very well compensated by Belgian standards. No employer is going to give anyone a 10% net raise just so they can work from home. It's much cheaper for $employer to invest in more office space. 100eur in office space gets you 100eur of office space, whereas every 100eur in net wages costs an employer roughly 250eur (wages+taxes+etc).
