Can I claim for loss of earnings if I have been signed off sick with stress and anxiety?

[Elly]

I have raised multiple complaints and grievances with my employer over stress and anxiety due to pressure in the workplace over the last 2 years.
I have been signed off sick with stress, anxiety and depression by my doctor after going to my GP, this is the second time this has happened.

Can I claim compensation for loss of earnings because I have been signed off with stress, anxiety and depression?
