I'm planning on resigning before Christmas and during our companies busiest time In 5 years, what do you think about this?
I think that's really unfair to the company, why wouldn't you wait longer?
The work environment does not please me anymore. I have seen enough of it.
It's not nice to only consider yourself in the workplace. You should consider your coworkers feelings as well.
I tried to work on it but it did not work out the way I expected.
I highly recommend you push through it, if you end up resigning early it would leave a bad impression on the company. Think about having the company is a good reference, this will help you out further down and finding a new job.
