We are a team of 6 developers:
• a lead (expecting a baby) • two (including me) experienced (more than 3 years) • 3 new joiners
We release process once in two weeks. We have more than 5 customers which company can not afford to lose.
The other experienced developer has an offer from another company with a very good salary (almost twice as much as their current one) and I can also get the same new job as my peer did.
In this situation can I negotiate a salary increment with my current employer without an offer letter, considering the lead will be on Maternity Leave after a month?
