Er no. Or at least they should not do so. They work the same hours as you. They are simply arranged differently. I take it you workin a school which (like those in the former Lothian Region) adopted an asymetric week? With the agreement of staff via the union reps, I take it? However, the 22.5 hrs max contact and 35 hour week still apply of course. Not ostensibly. You will be working the additional hours. The answer to that (if teachers in the school are as het up as you say) is to have the union reps enter into discussion with the HT to arrive at a modification to the school's working time agreement. The time can be claimed back from other days in which teachers are working on "collegiate activities".
