Not acceptable. Total piss take. Does he not need to be available when others are working? Not in the evening.
Well, if you've read the 3 pages of comments before posting this, you'd realise that no, not everyone needs to be working at the same time as other employees. It depends on your job.
As said on this page
Everyone’s work is different. I’m always surprised at how prescriptive some people are on these shorts of threads, as though the way their workplace does it is the only possible or correct way. It’s very strange.
It’s not fair if the whole team does not enjoy the same flexibility.
Though there is nothing in the OP's posts to suggest this is the case. Presumably - if doing the same role - colleagues could also choose to start earlier or finish later and have a bigger gap in the day? They have chosen not to, and are moaning about the fact a colleague has made a different choice.
He’s taking the proverbial. Wfh means you’re simply working in a different location - everything else stays the same, and that includes hours
But potentially his hours were flexible all the time anyway ? I know mine are. As long as you do your hours over the week, no-one minds when you do them. Some people like to start early and finish early, and some work late and some have lunch hours and some not. Different employers have different rules about flexible working - as has been demonstrated on this thread. I for one can work the hours I want to,, as long as there is a general pattern of being available during 'typical' working hours, but as @Fuwari said at the top of P4, I won't be able to pick up a call or e-mail that often as I will often be in a meeting, or on another call, or focusing on something I need to finish.
My employer doesn't have the money to offer reasonable pay rises, so it has looked at how it can improve T&C to improve staff retention, and one of the things they brought in about 18 months ago was exactly this - the "permission" to work your hours flexibly (as long as it fits with covering 'business need'). It is really liberating.
