I have an issue at work and I was hoping to get some help to propose a solution. Our company (an IT one) has issues in finding developers (I guess that's something common). But there are teams that are having hard times at work due to lack of developers. The manager is telling us that he has posted the job positions on several sites and the hr is looking for people, but they don't find anyone. As we proposed, give them a higher salary and people will come (the ambiance at work is on, the company is known as an ok one). But the manager told us that it will not be fair to give higher salary to the new guys and the older ones to receive the same salaries and when we told him to increase the salary and for the old ones, he said no. So what solution should I propose to the manager?
Take into account that this is happening in Spain and the company has the headquarter in Amsterdam and there the salaries are much higher, even if we do the same thing (actually, the core team is in Madrid).
