I find it unreasonable in times of extraordinary growth and profits to be asking for financial concessions from mechanics considering the double didget growth in our CEO's pay, which includes generous stock options, since 2012. The terms "unsustainable" and "safety issue" used as justification for certain "must haves" is ludicrous and insulting. I'm certainly open to common sense operational changes that would decrease flight cancellations and delays but at this time I'll be taking a hands off approach to language that removes thousands of dollars from my paycheck. Our contract is certainly unique in this industry and has drawn many talented mechanics away from Southwest's competitors with many years of valuable experience. Our sacrifice for leaving a high seniority position at the legacy carriers to start "at the bottom" is being met the outright hostility and disrespect. Mr. Kelly, I don't begrudge you your pay as you've been instrumental in building an awesome airline so please, don't begrudge mine.
