Depending on the type of business, and your position, when you are offered a permanent position, make sure there's a clause covering the schedule of your Raises and Promotions in your contract. You want it to be clear, and in writing, how much and when you can expect to get Raises and Promotions. Cut the very best deal you can going in the door. You decide what Raises and Promotions you get by everything you do every day in your workplace. Don't take it personally if you don't always get the amount of raise you desire.
Most employers base the amount on how much business they did in the last six months or year.
So these raises can vary from each review. They're not necessarily a reflection of your individual performance. And know that it's common policy for employers to always leave room for improvement. You can get a raise instead. But if you really believe you haven't gotten the recognition and raise you believe you have earned, you can go to your immediate supervisor and talk with them.
