I work in a small team. About 2 months ago a colleague announced he was going to be changing his hours slightly so he could start after lunch on a Monday and finish before 5.30 some days, but gave no real details.
A month ago he started starting work at 2 on a Monday and doing 3 x 1.5 hour sessions to make up for the time... at 9pm. We work in a regular 9-5 type role, no working with colleagues abroad or anything. This means every Monday morning myself and another colleague have to cover their work. Another colleague doesnt work on Mondays so we have that work too, but that's fine, they are PT. Predicably there are loads of interruptions at that time of day and lots of over weekend queries.
Colleague does not do any of our work in his extra hours. There was an incident a couple of weeks ago where there was an urgent query at 7pm which anyone could have answered, but it was left until the next morning. I'll admit I am bit suspicious that colleague is even working these extra hours as no evidence of it.
I know this isn't something I can change, but I suppose I'm asking for suggestions on how I can deal with the resentment?
