Do you like your company to invest in you by giving you courses and trainings or just to have salary increase ?

One of formula for success is to "First learn then Earn" so organization develop its prime assets through training and development. Go for training, then implement and this turn into growth! so keep learning keep growing.

First, training & development for enhancing new knowledge and skills then salary. However, both are equally important.

Although increase in salary will be good, it is short lived and will not satisfy the long term drive of a human. Therefor training and courses (if it is for personal development) will be more beneficial to an employee, as it enhances the employees skills and knowledge. This can be utilized by the employee within the organization, or in another organization.

Agreeing with all previous it should be learn then earn strategy. However both incentives should go some how inline to get employees max productivity

I believe training is one of the most important keys to any employees success and output in every organisation , The very fact  that the company is making an investment on the employee in terms of training and courses makes the employee feel important and valued as along with gaining new skill set , his loyalty towards the company increases ten fold and this reduces attrition rate in the company in the long run thereby reducing overall hiring costs for the company . 

The core fact remains that the company has an educated asset in its midst provided the right training to do the right job has been delivered by the right people . 

Of course I like to have courses rather than to have an increase since the more qualified I will be the more money I will gain

Yes, I like because if my company have an internal expert of an subject it will be an assets. 

In my opinion the best choice is a mix of this two because we are human beings and money are one of the main ways to motivate somebody to be performance, but in the same time there are a lot of people who prefer to work for company which invest in their education. In fact if the company see that the employee has better result after an investment it's normally to raise his revenue even you paid for his development. If you do not raise his revenue after a while he ll stop to be performance or worst he ll leave the company for another who appreciate him more. 

I would very much appreciate my company investing in me as long as its constructive and not just an online course that consists of word documents or training where the trainer is talking of some powerpoint slides. 

Dear Ms. Samar / Ms. Rania

Simply it is not they increase your salary or training courses to choose from.

Human capital is an organization investment so it is important to realize the difference and to consider the importance of each towards its business.

An employee that worked for a day in the organization is considered an investment and loosing that employee is considered a loss in that investment.

The organization has to combine both in different ways to protect its investment from losses.

If the employee did not receive the appropriate training towards his job and being up to date it would create losses to that organization while that employee still working and considered ok to a certain extent.

If the employee after a period of time did not have a raise, that employee would consider moving to another organization in order to promote his life and career in a different way, then it would be a loss towards that investment also.

Hope that gives you a closer look to what should be planned and considered in general as it is open and general question that might vary in its application in accordance to the organization and the job nature at that organization.

Thank you and good luck.
