I confess I have found myself quoting this at work a number of times 
over the past few months. But it was only recently that I stopped to 
think about what I really meant. Well not so much stopped as mildly 
ranted at a friendly colleague when discussing the latest work 
frustrations.
So here is my first "compare and contrast"
You get what you accept.... with a horse
In
 the horse world, this is normally about a rider/handler and the horse 
they are working with. There will be rare situations where a handler is 
working with multiple horses - driving a pair or four for example. But 
for most of us it is a one to one situation.
In the 
interaction with a horse we have to decide what our boundaries are, what
 is "ok" and what is "not ok". Anything we accept becomes, by accepting 
it, "Ok".
What is the difference between accepting and 
not accepting ? It's interesting how we humans tend to think of these 
things in terms of a BIG reaction. A BIG reward for getting it right, an
 equally BIG reaction of some form for getting it wrong. The reaction 
for the "wrong" result depends very much on your personal philosophy. 
But
 for a horse it can be something much smaller than that. A release can 
be a reward, and can be as small as an exhale. My second pony had a 
rough time in his youth - when we first got him he would *shake* if you 
raised your voice. When asking for something, Parelli talks about four 
phases - and uses the idea of "air, skin, muscle, bone" to give you the 
idea of how those phases progress. (I doubt many of us ever use a true 
phase 4. But in the same way, I suspect we tend to go in somewhere more 
than phase 1)
I think that makes the cue a negative 
reinforcer - as the required behaviour terminates the reinforcer. 
Initially they (Parelli) weren't into treats and thinking about it, even "rub to a
 stop" is a negative reinforcer (the rub stops when the horse stops). 
More recently the horsenality concept has meant treats are used with 
appropriate types of horses.
But that is straying into 
another subject, about rewarding wanted behaviour. "Accepting" can 
simply be that - no reaction, no reward, just accepting. Not accepting 
doesn't have to be a negative reaction but could simply be asking for 
the same thing again.
You get what you accept... at work
In
 a work situation, by contrast, we are rarely in a one to one situation 
and more often in a one to many or many to many context. Added to that, 
you aren't always in the leader role and may instead be in peer groups, 
or working across different levels of hierarchy within the organisation.
So
 in work, how does "you get what you accept" work ? While almost by 
definition there is an implication that if you don't want a particular 
behaviour to persist - you have to "not accept" it. But how acceptable 
is it to "not accept" something in work, especially if the unacceptable 
behaviour is from above you in the organisation hierarchy ?!
Is
 there a greater need for diplomacy in a work environment ? My initial 
reaction is yes, but I dislike the implication that I can somehow be 
undiplomatic with my horse. A horse tends to expect a much more 
straightforward or honest reaction, whereas at work people come to 
expect a certain amount of dissembling.
The reality of 
needing to keep your job, to pay the bills, simply does not form part of
 the interaction with a horse, but can not be escaped in the work 
situation. How much is it ok to compromise your integrity in the work 
place ? If the presiding culture simply does not support active 
challenge, where do you draw the line in terms of speaking your mind 
versus biting your tongue ? And if there is no option to "unaccept" 
within the work environment, is the only option to reject the entire 
work environment and change job ?
