does your work provide employee parking for cars?
If so; then one of the funnier ideas -probably heard it here
is to stick a dead van in one of the spots, and use it as a bike locker.

I'm a big believer in "it's easier to ask forgiveness than it is to ask permission." Surely you can find some place to put your bike that is out of the way. Don't talk to the boss, talk to another co-worker and ask if it's ok. I'd just bring it in and use good judgment in a place to put it out of the way and then see if someone tells you can't do it. Seriously, it's a little thing. The only way it's going to be be an issue is if someone complains about it and who would?

My experience has been that chain link fences are actually pretty secure. The trick is to anchor the bike at the vertical support post, (preferably with a u-lock encircling/straddling the post), the post is difficult to cut and the *fence* prevents lifting the bike up off the post.

Hipster High Lock ; Hipsters (generally late teen/twenty something, not necessarily bike messenger type) cyclists would lift their light weight "single speed"/"fixed gear" (SS/FG) bikes to the TOP of the 8 ft. tall chain link security fencing surrounding outdoor RAVES/concerts so that the handlebar would hook over the top of the fence, straddling a vertical post then u-locking the bike HIGH OFF THE GROUND.
RAZOR WIRE across the top of the fence? EVEN BETTER. They could then enjoy the entertainment without 'HARSHIN' THEY BUZZ', 'stressin' on they shway fixay gettin' ripped'.

Other cyclist seeing this, found that this technique worked extremely well on the 6 ft. and even 4 ft. tall chainlink (also called CYCLONE) fences. As long as the shorter fence had a horizontal 'spreader' bar or at least a thick steel cable running along the top of the fence between the vertical posts.

CAUTION : While the above techniques are well proven. RESIST the temptation to try to *hide* the bike in a particularly overgrown or 'OUT OF THE WAY' section of fence !!!
ALWAYS REMEMBER given time and privacy ANY locking technique/system can be cracked !!!

i just lock mine up outside of the office, that way I can see/hear when anyone is messing with it.

Looks to me that you've just proved that locking the bike to the handicap parking sign is safe for the bike.

My father-in-law is known to park-by-braille too, just check his rear bumper!!

The receptionist is up front and the sign is right in front of the building

I've also brought the front wheel in with me

I can't decide whether to lock up my frame and chain the back wheel, or just lock the back wheel in the triangle..

Decisions decisions

If there was nowhere to safe (implying a signpost is unsafe) I'd bring it inside.
-If there are objections, you could argue that the company pays hundreds if not thousands to maintain parking lots so people can bring their car and let it sit for 8 hours every day.
-It brings in dirt? Well, somebody is probably coming in and vacuuming/cleaning periodically anyways.
-If dirt an issue, perhaps you could volunteer to vacuum it up if you see it.
-In North America, that also represents ~50% or more of the square footage of the property. You could say that offering to bring your vehicle in with you and clean up after it is actually saving the company money.
-If there are more cyclists, band together and get a rack put in. In my experience, if people SEE that bikes are at work, its a visual indication that it can be done, and they are more willing to try it themselves.

I've never had to argue these things before, but you can quickly come up with a list of arguments in your favour.

I understand what you're getting at dude, I'm the only one that rides my bike.

But so far I've had 4 or 5 people coming up to me telling me that they want to ride their bike to work and seemed really positive about ir

did you try bringing it inside?

I'm not going to have a passive aggressive relationship with my management

You have common sense. All the people saying just bring it inside, and maybe no one will notice, especially since you have already been told no, are clearly more concerned about bicycle discrimination or some such than your livelihood. Unless you are in a union, NY is an at will employment state. You can be fired for not being a team player, voting republican, liking disco music, or just about anything besides being a member of a protected class. Being fired for insubordination (which is what doing something you were told not to do is) would be to easy. Don't over think it man, the post is away from the actual handicapped spot, in view of reception and in a private lot. Lock it up and don't worry about it, man.
