What is your reaction towards continuous false promises from administration concerning promotion, salary raise?

At first I'll try by sending a remiding messages  for the administration  

Then I'll ask for a meeting for futher understanding 

If the two issues yield for nothing, neither moral nor concrete, I will adopt the last issue:

Continue working while searching for another job.

First send messages with your genuine requests

and then for a meeting to know the Management stand to understand the real reasons 

(before taking decisions)

Continue working while searching for another job.

As i am currently doing the same thing.

Continue to work to the best of my energy with the search for another job is estimated my abilities

Ask for a meeting with management to understand the reasons behind delay..

Working in less power and motivation as a sign to the administration.

Concerned people (Management) ought to refrain from showing carrots because carrots are seasonal and creates situations of many types as listed in the question.

Such strategies are very short lived, generating waves of uncertainty within the most  valuable resource of any business entity.

Bench marks are to be achieved, set returns are to be earned and not donated or gifted and mutual acceptance is to be respected and adhered to for long lasting productive relationship.

I suggest that the individual who showed the carrots must be talked to in the presence of concerned authority.

First  ask for a meeting with management to understand the reason behind delay and if this dint work then i will continue working while searching for another job.

make meeting with management

and search for new work

1. Working in less power and motivation as a sign to the administration.
2. Continue working while searching for another job.
