M.:
Congratulations on your promotion. You must love your job. If your boss is asking you to get a degree, for what purpose? More pay, better computer skills? You need to determine first WHY you are doing this. Also, will they pay for all or part of it? If he wants you to go, then you need to see how much they really want you as a long term employee and what are they willing to pay to keep you. You have skills that are used in so many jobs that you really need to consider if that is what YOU want to do. Whose life is this anyway?
I was in Human Resources and I took night classes to get more experience on programs such as Excel or Word or Access because I lacked them and my job required them. I am more marketable now with better skills. Therefore, I am not tied down to this job. What is it that you want to do? There are many one day courses that maybe your company will pay for, but getting a degree in Secretarial Science is not absolutely necessary unless your company pays big money for it. Most companies pay by experience and with a title of Executive Secretary, you must have some pretty good skills. I am pointing out a different path here that you need to look at first before jumping into anything. Is this your passion? Does this company offer you more growth up the corporate ladder in a management capacity? Again, what is it that you want M.? Please don't let anyone decide your life for you. You are still a mom and have responsibilities as well. If this is going to get you what you want, then go for it. There are many suggestions, but first find out what it is that you are asked to do and why. I am assuming you like your boss and your employer so what are they offering you in return??
