There is a sicknote section in my contract with my employer...
I would get full pay for 26 weeks with fortnightly review by my GP and the works doctor. If you are very Ill and are forced to leave work due to ill health then you will get an agreed amount from the employer as a lump sum then some sort of negligible pension from the company as a pension...
If i die in service my mother would inherit £110,500 as a lump sum pay-off then a full pension for 5 years. after the 5 years the pension is halved for the rest of her life.
