Used to be a relaxed, self managed policy of when you came in the office. I would go in minimum 2 days a week, but some days more, some days less, just how it worked out. BT lied around a new hybrid working policy when building a new BT office. Through all planning and roll out of the new hybrid better workplace program alongside a new office (2yr long process), they said it would be 2 days in the office mandatory and then 3 days choice of home working or office working. Once they actually built the new office in Bristol and rolled out the program, it was minimum 4 days in the office and only 1 day a week working from home. I'd already moved house 18 months before.
