If you work 6 days on, 2 days off anywhere near regularly, then you clearly work for a crap company either flying 4 short sectors or you are including days off down route as part of your "work" which is not very clever. Move on, there's a massive demand right now for experienced pilots all over the world working a schedule that's more like 4 on 3 off (ultimately the routes and sector lengths) define how much you will "work".
