I'm sure masturbating at work happens a lot. Meh. British productivity figures aren't great but, hey, work to live not live to work. (Can wanking be included in GDP figures somehow?)
Masturbating at work, filming it and posting it online in a way that obviously is findable by others (that's kind of what online is, after all) is just plain stupid. I would expect to be on a knife edge at work at the very least.
Filming your personal kink and demonstrating that you don't acknowledge any boundary between your work for a children's organisation and your cock needs is really worrying. Sacking would be about the least I'd expect.
Then be shown to leap to employ controversialists who don't understand safeguarding for the same children's charity? This is just horrible corruption. I hope Peter Wanless reviews the entire organisational culture, particularly the employment of a Celebrity Manager - don't recall that from the fundraising adverts.
