morning talky
Maybe it's lack of sleep but could you explain what the difference is between your compromise and their new proposal? I was finding it a bit difficult to follow that bit.. And it would be useful to understand how far apart they are.
That aside, you can either formally appeal it or try and barter. I think you have been more than reasonable, you are not asking much, you have been prepared to do it on a trial basis and have been prepared to compromise as well. I do think it's likely that an appeal would be heard by someone different/more senior, so from that point of view it might be worth doing. I think if it goes to someone who is not involved, and you can show how reasonable you have been and the reasons they are giving for refusal aren't good enough, it is quite likely to be agreed at least on a trial basis.
So you could do that. Or you could try and barter with your manager. It does sound as though she may not be the kind who is up for that though, not sure. Is there a middle ground between the two proposals which would be acceptable to you? In which case you could propose that informally to your manager with a view to avoiding an appeal situation - she may go for that.
Have a look at the procedure for flexible working, I'm sure it will state who would hear an appeal.
It does sound like you are not in the best working environment and forcing a request through on an appeal won't endear you to your manager if she's a bit stroppy about it already, so that's worth bearing in mind. But if you are prepared to carry on working there at least for the time being and accept that your manager might be a bit uncooperative for a while then appealing it might be a good idea.
As i think I might have said many posts back, after a while, when your new working pattern is working well and is 'normal', how it was achieved will be more or less forgotten. It will be initially a bit difficult probably, but that should settle, and if it enables you to stay there and be making money, might well be worth it.
That was a bit rambly wasn't it?! Anyway, if you can clarify how far apart the current two proposals are that would be helpful, and see if you can find what the appeal procedure would be for this as well.
