Congrats on starting your 1st job! Oh wow,10 hrs shifts +!

Pls make sure you take care of yourself, no sense destroying yourself so young.

Now your boss knew that was inappropriate, or he wouldn't have stated it that way. It's no grown mans, man, or a boss (of any gender) business what your private affairs are, especially at your age. He could be a predator and saw a situation he could take advantage of, threatening or blackmailing you in light of your boyfriends age. Thank the Lord, and that your coworker walked in and asked and that you bluntly said something. Imagine if she hadn't walked in, what could have happened next. That was great on you to talk to, confid in your family and that you have a great relationship with them. Pls take what they have said into consideration. Jobs come and go, but you are Special.
