Too much to do, too
Where excessive workload is the problem you can do a self-analysis of your job. First look to see if there are ways to cut out low-yield work tasks. Use good time management tools and remember to delegate work to other people where you can.
Second, consider whether you are being too accommodating. Should you let people know that you have too much work to do? Should you be politely turning down new work that people pass you? If this is the case, then improved assertive communication may help you to do this in a positive way. Remember that you will have to say “no” at some stage; otherwise your commitments will get bigger and bigger. You must learn to say no to commitments that you should not take on; otherwise you will be in severe danger of becoming intensely stressed and exhausted.
An obvious point is to check that you are using all of the resources available to you. Included within this, make sure that you are using your support network as fully as you can and that you are getting the help you need when you need it.
Finally, be aware that it is just not possible to do some jobs. Sometimes organizations commit themselves to projects that they do not have the capabilities, resources or skills to complete. These quickly become “projects from Hell”. Beware of these projects - they can be traps from which it is difficult to escape, even if you are at severe risk of burning out.
