I think they've only given gardening leave to a couple of people they made redundant (which they weren't, and that was the point the company started going downhill).
There is zero chance of them offering gardening leave to me.
I haven't mentioned it at all yet - I had a notice letter printed and was planning to yesterday but there was no opportunity to get my manager alone.
I've used part of my outstanding leave to book the first week of October, so effectively it would have been three weeks notice, and I'm not sure how he'll react on Monday.
