I strongly disagree,
if you would like to obtain a high level function in a company at a later stage, your Masters will be an invaluable asset. And if you switch jobs in 5 or 10 years it will also make a difference on you CV.
If you do start working immediately, make sure you end up in a job where you continuously learn (and not continuously do the same tasks for your company). That will increase YOUR value, which is the most important in the long run.
