Ask HN: Ethics of applying to work at other companies
I'm 19 and have been working as a PHP web developer in the north of England for 7 months now, though I've been programming for 3 years. I am paid far under what everyone else in my position is paid, though I get bi-monthly (but small) wage increases.
The amount of money I currently get from my work is not enough for me to live off, after paying rent, travel to work and council tax, I only have £6 left every 2 weeks. My current food bill is £3 per week. £3. And I have no more money after that.
I have found another job which offers over 3x what my current job does, requiring experience in technologies which I use daily and some of which I am certified in (E.G. I have my Google Certified Adwords and Analytics certificates.)
What are the ethics of my applying to the other job for an interview and could my boss fire me if he knew I was looking elsewhere?
