A colleague of mine has been forced to take some time off due to illness. They've been signed off by the doctor, it was not appropriate to work (we're talking about a matter of weeks - not months or anything like that).
Throughout the period they've been in contact with their manager multiple times, and he has assured him that they should stay at home and assured them that they will be entitled to full sick pay. Unfortunately my friend has nothing in writing.
Having returned to work my colleague has discovered that they he will only be paid for a small proportion of his time off. Needless to say he's terrified how he's going to pay his mortgage!
We're based in London, what steps can my friend take? He feels like he's been fed incorrect information and is now in real financial trouble because of it.
