Does A Masters Degree Guarantee Jobs?

Since growing up I have always been accustomed to the idea of double up my degree.
Not like it's a bad thing but what purpose does it serve to run a Masters or PhD program in the long run.

My Dad is always telling me to do one program here and there. It gets tiring honestly as I don't consider myself an academic per se and I would only put in effort when I see something is absolutely necessary.

A cousin of mine once went to the UK for her masters, previously working at a brewery.
 

She told me that going for this program would guarantee her an upgrade in department level

Has anyone here gotten any similar experiences, share your story or those you know of. Were you ever selected for a job based on that or a promotion?
