I have intention to resign for better pay and benefits but my boss only intend to increase my current pay to match the offer. Should I leave or stay?

Leave. Your heart is no longer with the company already, no point staying. It’s the boss’ job to try to make you stay by matching the offer, you don’t have to accept it just because.

You can use math to determine the best package.

Longer leave is essentially more money too, you are paid to do nothing about work, so it's more money. If you work only on weekdays then one day of paid leave is worth your annual salary / (5 days *52 weeks ).

Total up everything to see if it matches your new pay from your current job.

And yes, what if it still matches??

WOW, that raise though. In that case, use other factors to decide:

• working hours (do you have to OT alot)

• career progression (do you get a promotion in the new company)

• work environment (what do people work there say about the company)

• colleagues and boss (do you like working with them)

Then also ask back yourself, why did you resign in the first place
