I must concurr with TENDOLLAR. I am in the same position having left Monarch pastures new last year, even with a Command looming. I also on average get between 13-15 days off a month. Duty free weeks, weeks of leave or just days off keep coming along.Even as a Senior F/O at Monarch I have received £1200+ payrise per month with stable rostering,which has enabled me to realise a life outside of the 'job', even as a junior F/O!!
I think the people at Monarch make the company what it is, they truly are a very professional and friendly group but I think that's only because the T&C's are so bad now it has brought the workforce together more so than in the past when I joined Monarch.
To reiterate what my colleague has suggested, look on Monarch as a training ground to get that valuable 'jet' experience before moving to another operator with better T&C's.
