All good points. It needs to be backed up by examples from the top.
I think, to be fair to my own workplace, they really are trying and have been attempting to reinvent their working practices regarding this kind of thing anyway for the last few years. There’s still a long way to go but they are notably better than I can imagine a workplace being ten years ago and much better than many others I know today.
Having worked in GI, I know just how...backwards some places can be. But these shiny start up type places don't even seem to appreciate a lot of their working practices are rubbish, never mind actually trying to improve them.
FWIW, one of my team had a baby just before lockdown and I told him to do whatever works for him and absolutely meant it. So he has. It's all about trust and treating people like grownups. (I also suspect my 'ultimately it's just a job and your health and family are way more important than that so really don't worry about it, if there are any issues we can sort them out' is maybe not really the approved message from senior management but hey .)
