Hi,

I used to work with some of the largest Banks in the city and yes they can be push and demanding. But in these days of increased monitoring and security they will want you back at work if you are likely to cause an error and more so if you are going to be a liability to yourself or the bank.

The doctor will usually be sympathetic to giving you time off and give you what is now called a "fit note". When you do start to recover the doctor can write special conditions on the note - e.g. light duties, reduced hours etc to reduce the impact.

Don't know how you get to work but I guess public transport to your office especially the Tube would be a nightmare at the moment because of the crowds, noise and bustle.
