Ladies...help me resign gracefully

[Indu29]

Hi all,
I have on sick leave at the moment but I have a job offer lined up which I would like to go for.
Now the crux is that I am due for a discretionary bonus payment from my current workplace 1week before my sick leave terminates. I have requested 2 weeks annual leave after my sick leave(I requested this leave 3 months ago and it still has not been approved).
If I resign straight after my bonus payment, it would mean that I would have to work for 3 weeks (I have a 1 month notice period to do).
I am not sure how to proceed because ideally, I would not like to work at my current workplace at all, I was planning to use 2 weeks AL and call 1 week sick and just leave.
Please ladies, help me come up with a plan to resign gracefully. I'm still a bit miffed about how I have given my line manager 3 months notice and he still has not approved!

Any chance when you resign they will tell you to pack up and go?

Many years ago I left a very unpleasant job (work ok, bully boss, coworkers awful, caused me mental distress. I was in my early 20s and keen to please). They refused to give me leave to get married (quiet period of business), then reluctantly agreed.

The day before I got married I gave HR my notice, which left 2 weeks to work. (I was later told all hell broke loose when they were told 😂. Apparently the whole building found their reaction hilarious 🤦‍♀️).

I was ignored for the 2 weeks so I spent the time adjusting the piles on my desk from one side to another and accelerated tasks for anyone I knew. I still feel very satisfied with myself.
