Let's imagine you have an employee who is highly self-satisfied with the work that he does and wants a salary increase. As manager, you have a rather different view of the matter. You have absolutely opposing views and cannot reach an agreement. What do you do in this situation? Instead of getting caught in "yes it is, no it isn't" arguments, you can take a look at the situation using the DiSCO model from Alan Seale.
This is a simple model that sets out 4 ways in which we deal with situations: 4 levels of engagement. Depending what level you are on, you are able to look at a problem in a particular way and to deal with it. Gaining some insight into which level you are at can help you to move on out of a deadlock. Here is an explanation of the four levels.
It should be clear that the choice and opportunity layers are the most constructive, including for the long term. So reflect before your meeting on who you want to be in this situation and what opportunities the situation offers. Ideally, also invite the other party to do the same thing. If that does not work, then you can also start the meeting by describing how you have prepared for it. That way, you lay your cards on the table and make a positive start.
Once you have the right mindset, the meeting itself remains. Of course, we have plenty of practical tips to give you here too.
Don't be afraid to ask for help.
Are you by nature someone who avoids conflict and who sees this kind of meeting as a mountain to climb? Training can help you to practise for these kinds of situations, making you feel more confident in yourself.
If you really can't come to a solution with each other, then there are other people who can help you. An HR colleague, company social worker or, for example, a company doctor can be brought in as a neutral meeting attendee (or to lead the meeting). If you involve them, they can help you and the other party to reflect on what is happening and what options are available. Professional mediation is the next step, ask your HR department about what is available.
