He had an ankle injury, it's been widely reported already. Squash is
not light exercise, escecially for ankles and knees. The guy was
taking advantage of the system and got caught. LUL followed normal
disciplinary procedure and the union has no case for a strike. If LUL
doesn't take legal action against the union for organising an illegal
strike, the passengers should.
