Basicly you can have the best padlock available, but if the chain is easily cut youre wasting money,D locks offer better security,but are limited to what you can actually lock them to as they have a short reach.

Get your company to increase the security of the bike shed.

To leave there or take with him? To make sure it doesn't get nicked or make it a bit harder.

If either of the former Pragmasis or Almax 16 or 19mm chain with Squire ss65 lock or something like and alarmed padlock like the Xena bullet.

Those chains are the only ones that will resist bolt crops, everything else will take little time.
