What will likely happen is your employer will tell you to go take a running jump, and then will ban ALL bicycles from being brought on site. I'm sure that will make you popular with your colleagues. You chose to use an expensive bike to commute on, that's your lookout. You could just as easily have bought a £25 hack bike and ride that to work instead. The self-entitled "I ride an expensive bike so I demand to park it wherever I want" attitude wouldn't cut any ice with me. I'd tell you in no uncertain terms to leave your bike out on the street if you used that approach on me.
The simplest solution to potential liability issues is to simply prohibit personal property like bikes being bought on to work premises. Problem solved.
You're just asking for trouble. Management could just ban storing bikes at work. You then try to bring a bike in regardless or complain if it gets damaged, and it could become a disciplinary matter for misconduct. On the other hand you could ride a cheap hack bike, park it wherever the manager will tolerate it, and don't rock the boat. If you insist on shitstirring because you want to prove a point, you'll likely come off the loser.
One problem is the C2W scheme, under which the bike was purchased.
@MontyVeda can correct me on this part, if I've misread his posts. Bike purchased under the scheme has to be new, from a recognised retailer operating the scheme, and then it's expected to be used to cycle to work.
Rules out getting a "hack bike" for £25, or thereabouts, from someone selling secondhand, to get rid off it. Not certain of the distance travelled to work, but "hack bike" or not, if damaged at work to the extent that it was unrideable, how is he supposed to get home?
Not everyone works only when public transport is running or where it may be running. Are you suggesting he stays at work if the bike is damaged at work, if he's no public transport.
It would save him the trip back the following shift that much is true.
