You see unter, unlike you I think the carrot and the stick are two different things. I hope you are familiar with the analogy I'm making. In behavior psychology they equate to reinforcement and punishment. With regards to reinforcement and punishment, you have a grand total of four options: apply reward, withhold reward, apply punishment, withhold punishment. To encourage a desired behavior, you can either apply reward or withhold punishment. To discourage an undesired behavior, you can either withhold reward or apply punishment.
The government is that entity with a legal monopoly on punishment, applying the stick. Criminals also have sticks, but they have them outside the monopoly. Businesses, outside government interference, do not have any sticks with which to motivate people, they only have carrots. They can either apply or withhold the carrot. No matter how badly you want that carrot, it is still not a punishment to withhold the carrot. Your option is to find a way to convince that business to apply the carrot, or if you cannot to go to another business and see if they will apply the carrot instead.
I do not see withholding carrots as necessarily immoral, but as amoral instead. It is immoral to steal a carrot. Applying the carrot can be moral, I have no revulsion to generosity, but that generosity must be freely given.
I do not consider the workplace environment to be dictatorial. Dictators have the power of the stick. The ability to say "you aren't doing your job, therefore no more carrots" is not a stick.
