For me I'm happy to go to office as long as I live near it, and working hours are flexible.

Unfortunately a lot of industries outside tech do not provide those. The cost of transport, especially the drainage of energy after squeezing into a crowded train / bus definitely outweighs utility bills.

However, if a company provides both options, remote workers are usually disadvantaged because of the reasons stated in the article and the comments.

It's a tough choice, and I think the division should at least be team-based for a fair competition.
